Application: elisa (0.3.0)

Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.15.0-39-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed:
  1. Set Music forlder for Elisa
  2. Wait for the library to update
  3. Added Pictures folder too
  4. Deleted Music folder from the list as I wanted a way to purge the database
  5. Nothing was purged so I scrolled down to see if maybe the bottom items where being deleted.
  6. Couldn't scroll too much as Elisa crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Elisa (elisa), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
