[Spacewalk-list] Clone of channel with identical label fails with error 500

[Patrick Hurrelmann]

Hi List,

I just was cloning some channels and mistyped the label of one, 
resulting in a duplicate label. This fails with an error 500 (internal 
server error). The error itself is correct for sure but maybe a better 
handling and a better error message is needed?

Stacktrace from admin-mail:

Error message:
