Volt "crash"

[spaetz]

1. Install volt
2. Run "volt serve" without any previous configuration in an empty dir:

Traceback (most recent call last):
...
File "/usr/local/lib/python2.7/dist-packages/Volt-0.0.2-py2.7.egg/volt/config/init.py", line 144, in prep_template
if hasattr(user_widget, func_name):
UnboundLocalError: local variable 'user_widget' referenced before assignment

And indeed, volt/config/init.py fails a few lines above "if the user does not have any widget file" and then bombs out on line 144 where the variable "user_widget" is supposed to exist.

Hi spaetz,

Thanks for reporting the bug :)! I just fixed this in f6d95d... It's showing the proper notification message now instead of crashing.

Thanks a lot for the fix :-) (I have a widget.py now, BTW).

A pity that you removed the line "# pass if the user doesn't have any widget file" I found it very helpful in the code that this condition would occur if the user had no local "widget.py". Care to reintroduce a code comment or should I send a pull request for that? :-)

Glad to help :).

That comment meant that the error should be ignored (instead of setting user_widget to None), so I removed it. I do agree that more comments can be helpful, though, so I'll put back another one in my next push.

Thanks again!

P.S. I'll be reviewing you pull requests soon so I can decide which ones to accept.
