            Bug ID: 381066
           Summary: Konversation crashes with a segmentation fault
           Product: konversation
           Version: 1.7.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: bugskde at takios.de
  Target Milestone: ---

Application: konversation (1.7.2)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.11.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Started Konversation. Automatically connected to snoonet and freenode. Joined 2
rooms on snoonet and 3 rooms on freenode. Did not send a message, only read.

I have no specific action that triggers the crash, it can happen while writing
or not doing anything with the application at.

I reported the bug at my distribution's bugtracker
(https://bugzilla.opensuse.org/show_bug.cgi?id=1041130) and was advised to
report this behaviour upstream.

The crash can be reproduced every time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
