Me too. Has happened to me twice now. Both times using totem to play an MP3 stream from the internet. This is on a MacBook Pro, 64-bi,t with ati X1600 and fglrx. I suspect an ATI problem (duh).
Steps to reproduce: go to wamu.org, click on 'listen live' and choose the 'mp3' stream. soon you'll be presented with your lovely gdm screen. -- [apport] Xorg crashed with SIGSEGV while playing a movie in Totem https://launchpad.net/bugs/85943 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
