I've been using audacious 2.1-1+b1 on linux 2.6.31-rc9 and I haven't had any
problems yet (I've only been using it again since yesterday).

So I went back in time for a while and tried audacious 2.1 under the 2.6.26
kernel... After about 2 minutes of playing, it suddenly hang, but this time
not only the audio, but also the whole interface and I could do nothing
about it unless I killed it.

Also, under 2.6.26, the whole desktop seemed a lot less irresponsive and
kind of "jumpy", as if something was occupying the CPU (even if there wasn't
anything special running). I don't remember feeling this when I used it
regularly, maybe I just got used to the most recent kernels so only now I
could feel a difference (even sill, it felt "weird").

I'm attaching the gdb output I grabbed after one of the audacious freezes on
2.6.26.

Regards,
Pitxyoki
