            Bug ID: 372655
           Summary: Baloo crash
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: julian at chipmusik.de
  Target Milestone: ---

Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-47-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
Whenever I start a VirtualBox VM the Baloo daemon crashes. Consistent behaviour
for several weeks now. I have Win 7 as a guest OS, but the crash happens
immediately when I hit the start VM button.  Random crashes happen without VM
use, too. But not as regular.

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".
