I have a similar problem with backingstore option enabled using kde4.2.1 under xorg 7.4 (xorg-server-1.5.3) xf86-video-ati-6.10.0. I'm using a radeon 9250 (r200 based) card.
When some dialog pop up or when i drag and drop a plasmoid to the desktop Xorg crash with segfault (the log is obtained in latter case). If i disable desktop effect Xorg crash at login.
If i disable backingstore the issue is not present.
