Bug#739194: blender: Segfaults at startup on armhf

[Gunnar Wolf]

I'm providing some further data points, guided by the kind souls in
#debian-arm ;-)

After installing gdb, blender-dbg and python3.2-dbg, I ran blender
through gdb, and got the following output:

$ gdb --args blender -b -noaudio

I'll try to peek a bit more into it, will post if I get anywhere further.
