How to reproduce (with roundup 1.0.1, tried for both
sqlite and anydbm):
1. start demo
2. add a new status 1234
3. create an issue with status set to 1234
4. Try to copy the issue
-> you will get an index error (see attached traceback)

The error will disappear if you rename status "1234" to
"1234a" or any other string that cannnot be converted
to integer. 

I found this in our customized tracker where we have
project names that are numbers most of the time (but
not always so that they are stored as string).
