I have been able to locate the problem: This bug appears ALWAYS when the users dont belong to the group "audio". However if i add them to this group, the problem disappears.
I dont understand that: If they dont belong to this group, should they still be able to play audio? What is this group good for and why do they have to belong to it? -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
