..more of a bug with rhythmbox, but the latest update to totem-pl-parser broke rhythmbox - in order for it to run, the following is required.
libtotem-plparser.so.12 -> /tmp/tcloop/totem-pl-parser/usr/local/lib/libtotem-plparser.so
Until such time as a more recent version of rhythmbox links against libtotem-plparser.so rather than libtotem-plparser.so.12, I guess I'll add something to the startup script to fix this.
