-- Information about the crash:
Dragon player crashes immediately after playing short (~5 minutes).

A bit of experimentation suggests that the crash also happens when playing .ogg files, but not, for example, when playing .avi files. (The AVI file I tried uses MP3 for its audio stream.)

The crash can be reproduced every time.

-- Backtrace:
