Comment 1 Mickaël 2010-11-21 01:32:53 EET

Maybe related to #475 (I could not reproduce)

Comment 2 Matti Airas 2010-11-23 06:26:08 EET

Agreeing that this is major - assigning P2. Let's not make this block the
upcoming release, however (or else we'll never get it done). We'll make another
beta soon after the first one, and this should be fixed by that time.
