I just reinstalled ubuntu dapper, and it looks to me that mozilla- mplayer is the cause. After I installed mozilla-mplayer and browsed a site, using a embedded media video, it crashed after a while. But the strange thing is that mplayer is not making it crash, but a popup dialog or something like that seems to trigger the crash.
I now uninstalled and everything seems to work fine... -- Segmentation fault in gtk_gc_get () https://launchpad.net/bugs/54043 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
