SourceForge.getRemoteProduct() returns an ASCII string; Product.remote_product expects unicode

There are errors in the update-remote-product output due to an encoding error with the SourceForge ExternalBugTracker:

Traceback (most recent call last):

This is because SourceForge.getRemoteProduct() returns an ASCII string instead of a unicode one.

The best thing to do is probably to make sure that the remote product is a unicode string before setting it in the update-remote-product script. This will ensure that the problem doesn't occur for any other bug tracker type in the future.
