We have issued an update (1.0.10-2) to fix a crash while playing songs with "track#" info missing in their id3. It's uploaded to maemo garage, and various repositories (bora/chinook/gregale) are being updated so it will appear in your Application Manager soon.

@luca:
This update also provides new remote commands:
"kagu -remote set_pause" to really pause playback (not toggle)
"kagu -remote play" to unpause playback
"kagu -remote volume_up" and "kagu -remote volume_down" for volume adjustments.

First two commands should come in handy configuring maemo-mapper to stop kagu music before flite announcements.
