Banshee freezes on start, requires force quit to exit

[Craig Maloney]

When starting up Banshee on an upgraded oneiric machine, it doesn't show the interface at all. Instead, I only see a blank screen before it turns gray, and requires a force-quit. I ran a strace -p against it, and it appears to be reading the filesystem, but there's no indication from the interface or the debug messages on the console that anything is happening.

Please let me know I can best help to diagnose this issue.

The bug occurs when the PC is not connected to internet. The extension that causes the bug is Ubuntu One Music Store, extension tested each one. Just do not know how to solve : )
After disable the extension is working perfectly so far.
Sorry my English.
