Application: baloo_file (5.18.0) Qt Version: 5.5.1 Operating System: Linux 4.4.0-21-generic x86_64 Distribution: Ubuntu 16.04 LTS -- Information about the crash: - What I was doing when the application crashed: This error message occurs during every session, and I assume that the lack of functioning 'search' facility in Dolphin is also related to it. It happens seemingly randomly, regardless of which program I am using or if I'm creating/deleting files, doing CPU-intensive work, or anything else. The crash can be reproduced every time. -- Backtrace: Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

When running balooctl check, the following terminal output is produced: mdb.c:2071: Assertion 'rc == 0' failed in mdb_page_dirty()
Closing as duplicate of a newer report, since the backtraces there are more up to date. *** This bug has been marked as a duplicate of bug 389848 ***
