ValueError in vevent parsing

[fabrepe]

Hello,

At first, thanks for this useful tool. But for my part it is unusable. I would like to use the script to retrieve owncloud stored icals but I got the following error: "ValueError: astimezone() cannot be applied to a naive datetime".

All day events (no start/end hours provided) are not causing error.

Thanks you again for your work.

Here is the print of a vevent leading to the error

Here is the stacktrace from ipython :

HI @fabrepe,

sorry for the late reply. You example is missing the timezone information for Berlin. Can you make sure it works if you use this instead?

I will release a new version with a bugfix later today.

I've release version 0.4.0 which includes this fix to pypi as well. Can you please test it? Thanks!

I apologize, i really had no time to check it. I am doing it with the new pip version (0.5.3).
