Application: baloo_file (5.38.0)
 (Compiled from sources)
Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-38-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
When ever I start DAVMail on my computer Baloo File Indexing Deamon crashes. Sometimes it seems OK, but then when I started Thunderbird Mail, I see the message saying Baloo File Indexings unexpectedly crashed.

- Unusual behavior I noticed:
Just before these happen I see no unusual behavior.
- Custom settings of the application:
I always start DAVMail manually when I need it. And it is mostly common settings as it comes.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
