[Pkg-audacious-maintainers] Bug#514674: audacious: Segfaults when opening ape file

[Luís Picciochi Oliveira]

Package: audacious
Version: 1.5.1-4
Severity: important

When opening some .ape files (encoded with Monkey's Audio codec), 
audacious segfaults.
Not all ape files make audacious fail. In fact, I only found one that 
does it.

This may be caused by the file's curruption, but I found that the file 
is still playable:

The current mplayer version at the repositories also fails with the 
following log (even if I don't use -afm mpcdec, mplayer crashes anyway):
> $ mplayer -afm mpcdec file.ape
(...)
> 
> Playing file.ape.
> libavformat file format detected.

However, using the mplayer version from the debian-multimedia 
repositories I can get playback, with the following output:

> $ mplayer file.ape 
(...)

This version displays that line saying "Error decoding frame", but plays 
the file well. Maybe this might help determining what is causing the 
crash in audacious?

Since the file is playable with this version of mplayer, it should also 
be so on audacious, or, at least, fail less dramatically, eg by 
displaying an error message instead of segfaulting.
