xorg crash during/soon after login in intel_renderbuffer_set_region

[Jelle Foks]

Using Karmic. After the latest dist-upgrade, with libgl1-mesa-dri_7.4.1-1ubuntu3_i386, my xorg crashes on my sony VGN-FW140E. After reverting back to libgl1-mesa-dri_7.4.1-1ubuntu2_i386, it runs fine again.

Disabling the mode switching doesn't help, disabling compositing doesn't help either. The only thing that I found that helps is reverting to the slightly older libgl1-mesa-dri package.

The crash happens during the login splash of kde, or when logging into a gnome session, it sometimes happens right after it shows the desktop, or after hovering over or clicking on a menu.
