Bug 416073

For some reason, the Kubuntu Crash reporting tool did not complete the crash report, so I saved it as a text file and copied it here:

Application: kdenlive (17.12.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Went into Settings, Configure Notifications. Selected "Rendering finished" notification, checked "Play a sound" and then picked a ".wav" file to play when rendering was complete.  I have this identical notification set in K3b when a burn operation has completed and it works fine.

FYI: there is a space embedded in the path (/home/john/Music/Fancy Sounds/Trumpet_Finale.wav) so I tried enclosing it in quotes; Kdenlive didn't crash this time, but the sound didn't play.

- Custom settings of the application:
None

The crash can be reproduced every time.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
