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

Select some files / a file and then from the context menu choose Compress > Compress to... and then select 7zip as compression method and press OK. Progress bar will apear in the notification area but when compression is done, it does not close. If I close it forefully using the X button, dolphin will crash.

The crash can be reproduced every time.

It has been reported several times in KDE bugfix and has been fixed.
