            Bug ID: 400304
           Summary: akonadi_imap_resource segmentation fault crash when
                    idle on GMail account
           Product: Akonadi
           Version: 5.9.1
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: IMAP resource
          Assignee: kdepim-bugs at kde.org
          Reporter: jlp at holodeck1.com
  Target Milestone: ---

SUMMARY
I was away at work and when I came back home I saw a notification that
akonadi_imap_resource crashed. It is with the IMAP account resorce which
connects to GMail accout. Actual version of Akonadi is 5.9.2, but it is not
available on the list of versions.

STEPS TO REPRODUCE
1. Have a GMail acount accessed via IMAP
2. Leave it idle so only regular checking of the mail might be active

OBSERVED RESULT
Crash with the following backtrace
Application: akonadi_imap_resource (akonadi_imap_resource), signal:
Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
28        return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
