I get a crash all the time in winetest since 1.0. Seems there is not a problem with any of the tests themselves (i.e. running make test).
The last few lines of output from winetest is: fixme:xrandr:X11DRV_XRandR_SetCurrentMode Cannot change screen BPP from 32 to 8 fixme:xrandr:X11DRV_XRandR_SetCurrentMode Cannot change screen BPP from 32 to 16 err:x11settings:X11DRV_ChangeDisplaySettingsEx No matching mode found 1440x900x24 @0!

I'm running everything on a clean install with an empty ~/.wine directory.
