Application: kded5 ()

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Yesterday, I modified the baloo file indexing settings to cover fewer folders. I left the system on overnight, with 2 GUI applications open: Chrome and Libreoffice Calc. In the morning, upon waking the computer from sleep, I saw this crash report waiting for me.

-- Backtrace:
Application: kded5 (kded5), signal: Segmentation fault
