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-b...@kde.org
Reporter: r...@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".
