Silly apport service

Unfortunately the developer was not able to uncover any problems with the logs attached. If you are able to reproduce this again, please feel free to attach new crash logs here, or better yet, open a new ticket. If you can get it to crash upon demand, a proper crash dump captured with gdb would be appreciated.

Thank you for trying to help!
