I haven't been able to reproduce this bug in ther computer. Computer 1 wheezy fresh install about two weeks ago, after upgrading packages three days ago it happened. Computer 2 wheezy "fresh" install months ago, after upgrading packages three days ago it happened. Computer 3 upgrade from squeeze to wheeze two weeks ago, after upgrading packages three days ago could not reproduce it, so...
This could be related with some especial configuration or something. I don't know, sorry for not being more helpfull. should we close it? cheers Iker
