Problem was solved after replacing linux kernel: upgraded from 2.6.38-2-amd64 to 2.6.39-1-amd64.
Peoples on forum report that 2.6.38-1-amd64 does not have this problem: http://www.linux.org.ru/jump-message.jsp?msgid=6296478&cid=6296624 Looks like problem appears while smplayer tries to fork mplayer. Either it is 2.6.38-2-amd64 bug or smplayer bug which is triggered by 2.6.38-2-amd64. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
