Rescan stalls if one of the directories in scan path is not mounted

[libertarian]

Running exaile while the partition with a directory in the scan path not mounted. The UI doesn't give an error message but just keeps on moving the scanning progress thingie in the lower left corner incessantly.
Terminal output on Ubuntu 10.10:

I see essentially the same output in terminal, however the scan path IS mounted via SMB. Bug did not happen under Xubuntu 10.04, does happen under Xubuntu 10.10.
