I have a reproducible crash in the radeon driver when using kdenlive and scrolling the project timeline). Driver version is the git code from 2010/12/15 (yesterday) but was also present in the pull I did on Oct 29.

Attached is my Xorg.log - looking at the offsets the crash was in EVERGREENComposite at the line

    vbo[0] = (float)dstX;

with a null pointer dereference - which pretty well must have resulted from radeon_vbo_space returning NULL.

If I disable EXA and use XAA instead it crashed in EVERGREENSolid, again when dereferencing the return value from radeon_vbo_space

This has been reported a couple of times eg https://bugs.freedesktop.org/show_bug.cgi?id=30945 and on the mailing list. I have slightly different hardware (an Asus EHA5450) so this does look like a real problem with the Evergreen code.

Other factors
Hardware: Core i7 920
OS: Fedora 14 (x86_64)
Kernel: 2.6.36
