SOLVED (and about to be re-opened as a more concise bug) Problem is that Xubuntu does not include as a standard package 'libgnomevfs2-extra', without which Totem cannot resolve URLs!
The crucial error is: << (totem-plugin-viewer:5357): libgnomevfs-CRITICAL **: gnome_vfs_uri_get_parent: assertion `uri != NULL' failed (totem-plugin-viewer:5357): libgnomevfs-CRITICAL **: gnome_vfs_uri_unref: assertion `uri != NULL' failed >> Comparing to playback on an fresh Ubuntu Hardy system, which includes libgnomevfs2-extra, this error is _not_ present. ------ Resolution: > apt-get install libgnomevfs2-extra For an extra 300k of disk space -- [Hardy] totem-mozilla fails to open quicktime trailer https://bugs.launchpad.net/bugs/262494 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
