With recent mesa (+kernel, xf86-ati) from git xbmc started crashing with the following error:
state_tracker/st_atom_array.c:417:setup_interleaved_attribs: Assertion `array->_ElementSize == _mesa_bytes_per_vertex_attrib(array->Size, array->Type)' failed.
Trace/breakpoint trap (core dumped)
[472553.996080] traps: xbmc.bin trap int3 ip:7f8bb4847586 sp:7fff827674d0 error:0
It either crashes on startup or when clicking on any menu item for the first time or when scrrolling the menu (without having clicked on anything).
I recompiled xbmca few times, it still does the same. Note that it was working until i did a mesa update from git a few weeks back.
The guys over the xbmc forums say that its a mesa issue.

Can you bisect?

mesa: fix crash in st/mesa after deleting a VAO
This happens when glGetMultisamplefv (or any other non-draw function) is
called, which doesn't invoke the VBO module to update _DrawArrays and
the pointer is invalid at that point.
However st/mesa still dereferences it to setup vertex buffers ==> crash.
