            Bug ID: 361681
           Summary: drkonqi crash in activateCallbacks
           Product: drkonqi
           Version: 5.6.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: rlk at alum.mit.edu

Following kontact (or kmines, or whatever else) crash on exit, drkonqi itself
crashes, which then triggers it in a seemingly infinite loop.  I'd be less than
surprised if there's a common root cause, but that's for investigation. 
Anyway...

Application: drkonqi (drkonqi), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
