Subject: Segfaults when reading my timidity configuration

Date: Sun, 30 Aug 2009 21:22:46 +0200

Package: audacious
Version: 2.1-1+b1
Severity: important

Audacious2 cannot handle my timidity configuration. From looking at
strace, when it reads "/etc/timidity/timidity.cfg", it follows the
include "/etc/timidity/eawpats.cfg" until it encounters the source
"gravis.cfg". The file is not found and audacious terminates by
segmentation fault.

WORKAROUND: Yet, the file is just not found, because audacious
ignores the "dir /usr/share/midi/eawpats" statement before the
source line. Putting the full path before the following sources
there makes audacious happy.

Still, there are two BUGS: First the application should not crash
due to a missing file mentioned in timidity config, second the
file is actually not missing at all, because the "dir" is a valid
statement in this context.

Below gdb backtrace to help locate the code:

tags 544339 - fixed-upstream
fixed 544339 2.3-1
thanks

In 2.3-1, the misbehaving "timidity" plugin is removed, and output to
Timidity is done through the ALSA sequencer.

Peace,
John Lindgren
