Comment 2 for bug 34232

I can confirm this behaviour on my Dapper too. As Jean-Christophe said, it seems to only happen when playing DIVX, and to randomly crash the system. When it doesn't crash the system, only totem crashes and displays an X error in the terminal (something like "bad match"). I don't have the exact error message because I can't take the risk to crash my system right now. If you really need it, ask me and I'll try to reproduce it later.
