VLC Subtitles Problem

Hi,
I am trying to play an avi file with embedded subtitles. I can see the subtitles track under Video>Subtitles Track, however I am not able to get the subtitles to show on the screen. The Messages window shows the following information.

main error: failed to open OSD definition file osdmenu/default.cfg
main error: creating OSD menu object failed
osdmenu error: osdmenu filter discarded

Does anyone have any suggestions on how I can correct this problem?

Thanks
