            Bug ID: 441614
           Summary: Crash to tty under kwin_wayland when Bluetooth Tablet
                    is connected
           Product: okular
           Version: 21.08.0

          Assignee: okular-devel at kde.org
          Reporter: malte.e at mailbox.org
  Target Milestone: ---

Application: okular (21.08.0)

Qt Version: 5.15.2

-- Information about the crash:
- What I was doing when the application crashed:
I connected a Wacom tablet via Bluetooth. Crashes like these have been
happening (about once a day or every two days) but I haven't found a way to
reproduce them. The backtrace is only shown for Okular, but all KDE
applications that have been running at the time produced a similar (probably
for the most part identical) backtrace (akonadi, kontact, dolphin, among
others).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Okular (okular), signal: Aborted
