Seems to work for me.

Please test if what I committed works too:

Jan,

I changed line 541 in lib/Horde/iCalendar.php, using the same patch as 
in bug 6641, so the preg_match_all is now:

if (preg_match_all('/BEGIN:([\W\w]*)(\r\n|\r|\n)([\W\w]*)END:\1/Ui', 
$vCal.'^M\n', $matches)) {

This seems to work for me. I can now do updates of contacts from my 
phone or Lightning.

Hi Jan,

I'm really sorry - I should have tried the patch from comment #3 first.
Couldn't believe it but this fixed the problem - contacts are syncing 
fine now.

There are some fields in the nokia e51 address book that don't sync  e.g.
the 'work e-mail' address. Can you give me / point me to some 
documentation how to
implement vcard fields in turba/syncml ?

Regards,
Ruben

Ok, here's another dump http://ruben.jenster.eu/sync-A123456

Created a contact named 'A' with mobile number '123456'
This appears also in data.txt

  Regards,
  Ruben

Unfortunately the data sent from the client isn't logged to data.txt. 
Can you please apply this patch and update your log files? Thanks.

Hi,

I can confirm this behaviour. Uploads from my nokia e51 mobile don't 
work for contacts with 1.1-rc4 but with 1.1-rc3 they do.

I put some logfiles online http://ruben.jenster.eu/sync-A123/
(Trying to upload a contact named A created on the mobile)
Hope that helps a bit.

Regards,
Ruben

How *does* the data look like? Check data.txt and the client_* logs. 
Also, please check if this is the same like bug #6641.

BTW, the /tmp/sync/log.txt around such an error looks like this:

Hi,

just tried RC4 of Horde Groupware Webmail Edition 1.1, and have some 
problem doing update of existing addressbook entries.

I have an entry synced to Horde, Nokia N95 and Thunderbird (using 
Funambol-Pim-Plugin-linux-v0.4.4.xpi). I've tried to update _one_ 
entry on both my phone and in Thunderbird, by trying to add a mobile 
phone number. One at a time. First Thunderbird, and then sync between 
Thunderbird and Horde, and later tried to update on my phone, and then 
sync my phone and Horde. Both of these seem to faile. In my 
/tmp/sync/log.txt I find this error in both cases:

ERR:    Error in adding client entry due to replace request: No vCard 
data was found.

This didn't seem to be the case with RC3, so is it a bug introduced in RC4?
