Bug 394965

Application: k3b (2.0.3)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.9.18-040918-generic x86_64
Distribution: Ubuntu 16.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I tried to configure the filenames of the audio tracks: e. g. I type %{title}, when 1 or 2 characters have been typed after the leading %{ k3b crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: K3b (k3b), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
