           Summary: IMAP agent strange behaviour and crash
           Product: Akonadi
           Version: 4.4
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: libakonadi
        AssignedTo: vkrause at kde.org
        ReportedBy: matthew at theleachfamily.co.uk
                CC: kdepim-bugs at kde.org


Version:            (using Devel)
Compiler:          g++ 4.4.3 20100127 used the debugfull cmake parameter.
OS:                Linux
Installed from:    Compiled sources

I first noticed the collections weren't being populated, specifically an IMAP
resource that I had created to connect to my IMAP server. I opened up
akonadiconsole to check the status of the sync. It had halted at 44% in a
certain folder. After this I tried to abort the sync, however, whenever I tried
to abort I got this error:

"akonadiconsole(13995)/libakonadi Akonadi::AgentInstance::abortCurrentTask:
Unable to obtain agent interface".

After a restart of Akonadi (which took a good two minutes), I restarted the
sync on the IMAP agent. It then got to a different folder, and the job progress
began to count down from 23% back down to 1%. I again tried to abort the job,
no errors and no change in the progress of the agent. I finally tried to click
on the 'configure' button but the agent crashed and I got the following
backtrace;

Application: Akonadi Resource (akonadi_imap_resource), signal: Segmentation
fault
41      int result = INLINE_SYSCALL (wait4, 4, pid, stat_loc, options, NULL);
