            Bug ID: 371738
           Summary: Crash trying to part #radeon
           Product: konversation
           Version: unspecified
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: luke-jr+kdebugs at utopios.org
  Target Milestone: ---

Application: konversation (1.6-branch #4910)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.21-gentoo x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:

Right-clicked on #radeon channel and tried to part it. I was prompted to
confirm, and when I clicked the Yes button it crashed. After restarting,
attempted to do the same, and it crashed again. This was before the part
command got sent to the server, leaving me in the channel when Konversation
started back up.

I was able to part #radeon successfully only by switching to the status tab and
typing /part #radeon

The crash can be reproduced sometimes.

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