mirrormanager causes python error

[Thomas Lenggenhager]

Hi

I succeeded in adding my host. However, now I can no longer access 
mirror.switch.ch I added. When I request
   https://admin.fedoraproject.org/mirrormanager/host/14
I always get the following error page:
500 Internal error

The server encountered an unexpected condition which prevented it from 
fulfilling the request.

Page handler: <function _wrapper at 0x2dc6398>

Thanks for fixing it.

For the Country field, some guidance would be helpful. Full English 
Name, two letter ISO code or what to use?

In addition to allowed countries you could also add something like 
world-region or continent to group the entries, when the list grows. 
Africa, Asia - Pacific, Europe, Middle East, North America, South America.

Otherwise, the interface is pretty straight forward to use.

Regards,
Thomas

BTW: I tried to use an accented character in the comments field. That 
caused also a Python error. So I removed it again.
I wanted to write 'On Internet2 & GÉANT2' and now I only wrote 'On 
Internet2 & GEANT' without accent on the E. That works.
