--- Comment #1 from marvi...@gmx.de ---
here is another one. This time I attached gdb to baloo_file_extractor and
waited for the segfault. The one above came from a core dump. Somehow, this one
here looks different. Also, there seem to be some kind of overflow. I ran
balooctl status right after the segfault:
# balooctl status
