Hello Alec,
hello Devs,
 
could you please look at http://pear.php.net/bugs/bug.php?id=17039 ? My google_contacts and plaxo_contacts plugins are affected by this bug (http://code.google.com/p/myroundcube/issues/detail?id=40&can=1)
 
Maybe Roundcube Core is affected aswell. If there are no concerns I suggest to apply the patch.
 
Regards,
Roland
