Comment 4 for bug 386375

I tried to look into this one and it seems like it originates from jockey/ui.py line 622:

self.error_message('', str(e).splitlines()[-1])

This is supposed to catch a generic SystemError and should probably read something like

self.error_message(self.string_error, str(e))

I am not much of a python programmer, but this should be easy to fix if you know what you are doing. Obviously it would be even better to present a more specific error message depending on the type of exception.
