Nice shot!

Try this shot in the dark fix attempt.

That's because there are 2 query calls in IMP_Folder::generateMbox().   
One is for size only, the next is for envelope, imap date, and 
fullText of the message.

This is correct - the object has the size information (key 12).
For some reason, the call to grab the full text of the message is 
resetting the results array.

It looks good until there. For some reason this code is called twice, 
but both times the $ret contents looks fine:

array
   1 =>
     object(Horde_Imap_Client_Data_Fetch)[439]
       protected '_data' =>
         array
           14 => int 1
           13 => int 39078
           12 => int 5796

and

array
   1 =>
     object(Horde_Imap_Client_Data_Fetch)[477]
       protected '_data' =>
         array
           14 => int 1
           13 => int 39078
           9 =>
             object(Horde_Imap_Client_Data_Envelope)[591]
               protected '_data' =>
                 array
                   'date' =>
                     object(Horde_Imap_Client_DateTime)[592]
                       ...
                   'subject' => string '[Tickets #8353] Re: Sort out 
LDAP preferences mess with user bindings' (length=69)
                   'in_reply_to' => string 
'<whups-8353-fa27ef3ef6570e32a79e74deca7c1bc3@bugs.horde.org>' 
(length=60)
                   'message_id' => string 
'<20090616114609.ooocc4w@bugs.horde.org>' (length=39)
                   'from' =>
                     array
                       ...
                   'to' =>
                     array
                       ...
           11 =>
             object(Horde_Imap_Client_DateTime)[593]
               private '_datetime' => null
               private '_error' => boolean false
               private '_string' => string '16-Jun-2009 17:48:14 
+0200' (length=26)

but after the _fetch() call, in the second run, $ret is empty. so 
these are contents of $ret after _fetch():

array
   1 =>
     object(Horde_Imap_Client_Data_Fetch)[439]
       protected '_data' =>
         array
           14 => int 1
           13 => int 39078
           12 => int 5796

and

array
   empty

In a mailbox with 1 message, I get the following for $ret:

array(1) {
   [1]=>
   object(Horde_Imap_Client_Data_Fetch)#228 (1) {
     ["_data":protected]=>
     array(0) {
     }
   }
}

For cached data ($data):

array(1) {
   [1699]=>
   array(2) {
     ["HICenv"]=>
     object(Horde_Imap_Client_Data_Envelope)#230 (1) {
       ["_data":protected]=>
       array(7) {
  [snip]
     }
     ["HICdate"]=>
     object(Horde_Imap_Client_DateTime)#234 (3) {
       ["_datetime":"Horde_Imap_Client_DateTime":private]=>
       NULL
       ["_error":"Horde_Imap_Client_DateTime":private]=>
       bool(false)
       ["_string":"Horde_Imap_Client_DateTime":private]=>
       string(26) "23-Nov-2010 12:11:02 -0700"
     }
   }
}

And for the second $ret:

array(1) {
   [1]=>
   object(Horde_Imap_Client_Data_Fetch)#228 (1) {
     ["_data":protected]=>
     array(4) {
       [14]=>
       int(1)
       [13]=>
       int(1699)
       [9]=>
       object(Horde_Imap_Client_Data_Envelope)#230 (1) {
[snip]
       }
       [11]=>
       object(Horde_Imap_Client_DateTime)#234 (3) {
         ["_datetime":"Horde_Imap_Client_DateTime":private]=>
         NULL
         ["_error":"Horde_Imap_Client_DateTime":private]=>
         bool(false)
         ["_string":"Horde_Imap_Client_DateTime":private]=>
         string(26) "23-Nov-2010 12:11:02 -0700"
       }
     }
   }
}

You are both using caching.  Check to make sure the default fetch 
entries are set correctly (Horde_Imap_Client::fetch(), line 2080; $ret 
variable).  $ret should be an array with sequence numbers as keys and 
empty Data objects as values.

Then check the cached data in Horde_Imap_Client_Base::fetch() (line 
2117; $data variable).  Make sure that cached data is valid.

If all looks good, check to make sure the return variable is still 
correctly set before we start calling _fetch() to grab the data we 
don't have (line 2204; foreach loop).

Same here. I tried to step-debug it, but I got completely lost in the 
Imap_Client code. Several times.

Empty Array() for me.

One place to start: what IS the value of $size returned from the 
fetch() call in IMP_Folder::generateMbox()?

Someone else will have to track down because I can't reproduce any of this.

I'm getting this error too now. $size is an empty array there, even 
though the server seem to return the correct answer:

I'm using traditional view.

Works fine for me - I don't see this.

I don't get this error, but a different one, even after fixing the encoding:
