Application: baloo_file (5.16.0)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.2.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
I copied a rather big folder tree (about 6GB, several sub- and subsubfolders and a lot of files).
Shortly after, I got the crash report.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
