Same here. It only crashes if xinerama is enabled. If I disable xinerama, qt apps can be run ok. Tested with Lucid and Meerkat, also tried newest beta of the nvidia drivers (260.19.04), same result.
Log shows a little more info: Backtrace: [ 378.165] 0: /usr/bin/X (xorg_backtrace+0x28) [0x4a0fa8] [ 378.165] 1: /usr/bin/X (0x400000+0x60fcd) [0x460fcd] [ 378.165] 2: /lib/libpthread.so.0 (0x7f12f9be8000+0xfb40) [0x7f12f9bf7b40] [ 378.165] 3: /usr/bin/X (0x400000+0xbb22f) [0x4bb22f] [ 378.165] 4: /usr/bin/X (0x400000+0x2c2d9) [0x42c2d9] [ 378.165] 5: /usr/bin/X (0x400000+0x2184b) [0x42184b] [ 378.165] 6: /lib/libc.so.6 (__libc_start_main+0xfe) [0x7f12f8b53d8e] [ 378.165] 7: /usr/bin/X (0x400000+0x213d9) [0x4213d9] [ 378.165] Segmentation fault at address 0x4 [ 378.165] Caught signal 11 (Segmentation fault).
