Application: amarok (2.8.90)
KDE Platform Version: 4.14.30
Qt Version: 4.8.7
Operating System: Linux 4.10.17-200.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

-- Information about the crash:
- What I was doing when the application crashed:
Amarok hadn't been used for a while and was taking a while to respond.
I removed items from a dynamic playlist before the UI had fully refreshed.
My music collection is NFS-mounted so initial reads can be quite laggy.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
