Totem erroneously launches 'gstreamer-install-codec' which then crashes.

Binary package hint: totem

Installed 2009-7-18 daily release of karmic-desktop-remix on Asus EEE900 netbook.
When attempting to play an MP3 file(by double-clicking on the file icon in file browser (files are on an SD card))- totem is launched but claims it needs to install a codec to play the file (vanilla MP3 file).
The 'search for codec' dialogue is launched ('gstreamer-install-codec'), which displays a single codec ('Gsreamer plugins for wavpack, mms, quicktime ...') and then crashes.. totally unresponsive, unable to close, cancel or exit. There is nothing in any log files (that I can find).
Going into system monitor and killing the gstreamer-install-codec process then allows totem to continue and it starts to play the file. This is reproducible every time Totem is started, but once running it will continue to play files from the playlist OK.
