There's a lot of noise there but no backtrace. In case you couldn't find it in the tutorial, the gdb command to get a backtrace is "backtrace".

Are you still interesting in having us look into this problem? If so, we need a backtrace.

Okay, this is progress, but you apparently have a version of Audacious with no debug symbols. See if there is an audacious-dbg package you can install.

i installed audacious-dbg and audacious-plugins-dbg (now version is audacious 3.6.1)
