Comment 7 for bug 62637

I can confirm this behaviour, but it's not just when you enable scrobbling in Banshee during the current session. It was happening to me even though scrobbling had already been enabled (i.e., it was already enabled when I ran Banshee).

The problem does appear to be with Network Manager. I was using a manual network configuration with a static IP address (needed to forward a port to this laptop). Switching back to roaming mode corrected the issue.

The oddest thing is that when using the manual configuration, Banshee scrobbles all the activity that hasn't been scrobbled, then it just stops scrobbling after that.

Banshee 0.13.1
Ubuntu Gutsy 7.10
2.6.22-14-generic
