Application: kmid (2.4.0)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-32-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
Load QSynth
Open MIDI file with KMid, either directly or via Dolphin
KMid crashes immediately on opening file.

Notes:
1. This is 100% reproducible for certain MIDI files, but there is no problem with the great majority of MIDI files.
2. These files were created in Rosegarden and play perfectly in that program.  Many other files also created in Rosegarden are no problem with KMid.

The crash can be reproduced every time.

-- Backtrace:
Application: KMid (kmid), signal: Segmentation fault
