#76 Rarely 'iteration over non-sequence' exception on Juice exit

[Anonymous]

Occasionally, Juice reports on an error when closing it in the progress of several podcasts download.

Juice.exe.log in the Juice directory will contain:

Exception in thread Thread-68:Traceback (most recent call last):
File "threading.pyc", line 442, in __bootstrap
File "ipodder\threads.pyc", line 94, in run
File "gui\tree.pyc", line 212, in _scan
TypeError: iteration over non-sequence

It happens randomly, can't give exact steps to reproduce.
