moreover the "check geometry" tool seems to go nowhere when used on this vector (but it doesn't crash nor freezes qgis).

Replying to lutra:

moreover the "check geometry" tool seems to go nowhere when used on this vector (but it doesn't crash nor freezes qgis).

the crash is gone in r12277. And AFAICS check geometry is just incredibly slow - seem to hang at 3%, but it's still. I'm at 10% now - 3rd feature and counting...
