Hi,
Since yesterday, I've been getting segfaults with every single GNOME or GTK2 application that tries to display a file browsing dialog ("Save as..." for instance). I can't even add an attachment to this email either without sylpheed (gtk2 build) segfaulting, so inlined is a backtrace obtained from running gedit and going to "File -> Save as...". I'm posting here since I'm not even sure against which component I should file this bug (gnome-vfs2? libbonobo? glib2?).
Try killing gnome-vfs-daemon, may require a relog. Apparently there was some issue about the internal protocol changing.
