Application: baloo_file (5.15.0)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:  Applying new file system to USB stick using KDE partition manager.  Baloo reported crash while indexing new incomplete file system.  Note that this bug reporting system is a very obtuse process, not really sure if this will be relevant information.  This crash seems similar to two others yet the method of 'attaching' this report to that similar bug seems impossible to execute only leading to an endless loop of select, +suggest similar then go back??? good luck.

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