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:

When I send an email I get an alert about baloo crashing.  This doesn't appear to be related to bug 362222 which is the only suggestion DrKonqi finds for this.

Looking at the logs in my .xsession-errors file I can see (this crash is the one corresponding to the backtrace):

 New Notification:  "E-Mail Successfully Sent" "Your E-Mail has been sent successfully." -1 & Part of: 0

KCrash: Attempting to start /usr/bin/baloo_file from kdeinit



Here is a second example (triggered by sending myself an email for this purpose - not the one that this backtrace is for):

 New Notification:  "E-Mail Successfully Sent" "Your E-Mail has been sent successfully." -1 & Part of: 0
Database "akonadi" opened using driver "QMYSQL"

The crash can be reproduced every time.
