Using QGIS-master (nightly build repo) on Ubuntu 11.10 I get even worst results. QGIS crashes when dissolving, using the Spatialite sample data set (layer "regions")

[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
qgis.bin: ../../src/xcb_io.c:178: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.
Aborted

I confirm that clipping returns an empty layer.

Seems this is more complex problem, I also found that many geometry operations don't work with SpatiaLite layers even from Python console.
