            Bug ID: 381172
           Summary: X11 crash while editing MPD.
           Product: kwin
           Version: 5.10.2
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kwin-bugs-n...@kde.org
          Reporter: darkhalo...@gmail.com
  Target Milestone: ---

Application: kwin_x11 (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.3-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- Custom settings of the application:
The window manager didn't crash. I could hovere over application tiles and they
would activate but nothing was able to be clicked. I even got tile previews for
the windows but no X interaction. This all happened while I was setting up MPD
with ario. I was connected to the MPD service but X stopped working after I
clicked "Update database"

The crash does not seem to be reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
