FLAC DSF doesn't properly send length data to last.fm (audioscrobbler)

Hi, this is my first bug report so I hope I'm doing this properly. I just installed the latest stable version (0.71.0946) on a Windows XP Professional SP2 box. I also have the Last.fm scrobbler enabled.

Here's the issue: when playing FLAC files from within Windows Media Player 11, the last.fm program says "Can't scrobble: track too short". ("Scrobble" means to get the track metadata and send it to my profile at the last.fm website.) The last.fm program ignores any tracks shorter than 30 seconds; this does not apply to the songs I'm listening to.

So the last.fm program knows what song I'm listening to (it brings up the song information in the last.fm window automatically) but it appears that Windows Media Player is not reporting the song length to the last.fm player.

Anyway, I'm not sure if this is a bug with the FLAC DSF or with last.fm... anyway, thanks for your time!
