It´s returning a NULL value only for the "trash" array member, which 
was supposed to be an object, and that´s why the error occurs only on 
line 67.

Here´s the debug info:

2011-06-03T20:16:14-03:00 DEBUG: Variable information:

If I set the option "When deleting messages, move them to your Trash 
folder instead of marking them as deleted?" to 'true' under IMP 
Preference, then a "Trash" folder is automatically created and the 
fatal error msg goes aways. Then, debug info shows this:

Thanks.

Looks like IMP_Mailbox::getSpecialMailboxes() is returning some 
incorrect value. What does it return at the start of that excute() 
method?

var_dump the variable $val just before that line returned: NULL

And the Horde::debug($val) returned:

2011-06-02T21:47:42-03:00 DEBUG: Backtrace:

Thanks.

What is the content of $val in that line?

Horde::debug() documentation: http://wiki.horde.org/Doc/Dev/DebugH4

horde 4.0.5 and imp 5.0.5

On every new login, the first time I click on "mail" module , I get this:

Fatal error: Call to a member function create() on a non-object in 
/var/www/horde/imp/lib/LoginTasks/Task/Autocreate.php on line 67

After hiting refresh, the error disappears, but only until next login.
