-- Information about the crash:
- What I was doing when the application crashed:
Today around 15:00hrs Brasilia time, I did an update of the system where several kde plasma packages were updated! my system was up to date, these updates appeared today! until yesterday there was only wine to be updated.. after updating the error appeared, I restarted and the error persists whenever I click to open the app it fails, always!

The crash can be reproduced every time.
