Created attachment 49760 [details] Backtrace Version: SVN trunk (KDE 4) (using Devel) OS: Linux Every time I launch kontact (or any other Akonadi-enabled application) the imap_resource crashes repeatedly until Akonadi finally disables it. The debug window in akonadiconsole gives: AgentBase(akonadi_imap_resource_8): No message retrieved, server reply was empty. Which may or may not be directly related to the message. From looking at the backtrace (which I will attach), it seems that what is happening is that the "slotDeliveryDone" slot is activated while the current task is a "SyncCollection" task which triggers an assert since the resource expects only "itemFetch" tasks to be active then. The IMAP server is a Kolab server which has both mail folders and calendars/contacts folders. Synchronization never successfully completes and I am unable to "subscribe" to folders. Reproducible: Always Steps to Reproduce: Create an imap resource. Try to synchronize it. Actual Results: An assert is hit. Expected Results: Synchronization should complete successfully.
One thing to note is that I pulled up the crashed process in gdb and did: (gdb) p scheduler->currentTask().type $4 = Akonadi::ResourceScheduler::SyncCollection So, the current Task is a SyncCollection task. There are some similar bugs, but none of them involve a SyncCollection task. I tested this several times and this is always exactly what happens. I've also deleted and recreated the resource several times with no change in behavior -- it still crashes.
Oops. I forgot that I'm not running latest trunk of kdepim. This is with kdepimlibs-4.4 and kdepim-4.4. Everything else on my system (kdelibs, kdebase, kdesupport, etc.) is running from latest trunk.
