Serious bug: the file requester freezes the viewer in Ubuntu 12.04

It seems that this previously announced bug on Ubuntu 12.04 is more serious than initially assumed, and also is still not fixed.

From reports on the FireStorm bug tracker it seems that it is based on a packaging bug in Ubuntu itself, and affects everything in the viewer that opens a “open file” requester … snapshots, uploads, etc.

Do not update to Ubuntu 12.04 yet.
