-- Information about the crash:
First of all, apologize for the bad English, because English is not my native language, so I have to resort to machine translation.
- What I was doing when the application crashed:
When I tried to use Muon Package Manager to install package digikam,it crashed.After that,I open the Muon Package Manager,package digikam has been installed.Then I reinstalled the package digikam without any errors.I want to know why this is.

The crash does not seem to be reproducible.
