crashlog on entering fullscreen

Any fullscreen app crashes right after switching to the fullscree even with the
same resolution. Windowed mode works just fine. I don't know when it started
because I almost always run games in window and make it fullscreen with the
Awesome WM. Today I've tried some old demos (you know, demoscene, 64k EXE with
astonishing visuals and music) and all of them crashed, suprisingly. I remember
them working well. Even steam games crash after they change resolution but they
work fine in the window. I tried Wine 1.4.0 to be sure it's not a regression
and the result is the same. NVIDIA introduced some changes to XRandr support
some time ago so this may be a clue. The backtrace and memory map attached.

My specs: Debian Wheezy GNU/Linux, Core i7 2600, 16Gb RAM, 2.5Tb total HDD
capacity, NVIDIA GeForce GTX 560 Ti, driver version 295.49 and 302.11 (both
lead to crash), Wine 1.4.0 and 1.5.5 (no difference, both compiled by myself,
vanilla source from git). I've tried this demo:
ftp://ftp.scene.org/pub/parties/2008/nvscene08/demo/stargazer.zip crashes
everytime it's launched with fullscreen checkbox set and works just fine
without it. Native games like Wesnoth work fine, tried 1024x768 and native
1920x1200 in fullscreen, no crashes.
