Does --disable-aso (which fixes the problem) disable soemthing in the compiler tools, or this just disables some written beforehand assembler code which is supposed to work better?

Indeed, it seems to be a problem in the architecture specific
optimisation for ARM.

I think for now I'll disable the ASO on arm. The assembler there is
quite old, from 2001 according to copyright. If someone wants to update
it they are more than welcome.
This bug causes rhythmbox to crash on ARM (e.g. Nexus 7) when
gstreamer1.0-plugins-ugly (which links to libmad0) is installed.
