Thanks for your bug. Could you get a backtrace with libgnomevfs2-0-dbg and maybe a gnome-utils debug package (https://wiki.ubuntu.com/DebuggingProgramCrash) installed?

It looks like there is a problem with the filename thats beeing created from the windows name, to long or to much bad characters (URI in URI problem?)

Thanks for the comment. The crash is due to the "%" from the filename. I've forwarded the bug upstream: http://bugzilla.gnome.org/show_bug.cgi?id=319188 and made a patch for it
