After updating to Banshee 2.2, syncing to iPod is successful, but leaves a phantom operation running with no description. The operation cannot be "stopped," but the iPod can be disconnected.

Images are attached.


== Dialog box when clicking red "X" button ==

Stop Operation

This operation is still performing work. Would you like to stop it?


== Dialog box when trying to close Banshee ==

Important tasks are running

Closing Banshee now will cancel any currently running tasks. They cannot be resumed automatically the next time Banshee is run.


== Terminal output at time of iPod sync ==

== Steps to reproduce ==

1. Click "Sync" button to sync to iPod (mine is a 4th generation Nano)
2. Two operation progress bars appear, one that says "Syncing iPod" and another with no description
3. After the sync succeeds, the "Syncing iPod" progress bar disappears, but the other one remains
4. Clicking the "Stop" button next to the remaining operation (and confirming in the subsequent dialog) does not remove the operation, but instead just adds the text "Stopping..." above it
