IndexError: string index out of range

I cannot reproduce this on projects.edgewall.com/trac/ at this time.

Nor on my internal source:/trunk/@2861 installation.

I can't reproduce either. Trac requires a query string of at least 3 characters, so the above query is rejected since it's too short.

Your config doesn't change the fact that you need to enter a query of at least 3 characters, and your example above only includes 1 character in the search string. Please check if you've made local modifications that are broken, or provide more information to reproduce the problem.

Try instead searching for the letter F.

It looks like the quickjump code is run before the length check. This is probably so that #1 takes you to ticket:1 instead of telling you your query is too short. If you enter just one letter and it is upper case the bug is triggered. That is, kwd[0].isupper() passes and kwd[1].islower() raises the IndexError?. Adding a len(kwd) > 1 at the front of the elif test or as guard to the whole function (as none of the clauses can pass with len <= 1) should fix it.

Thanks for the clarification. Fixed in r2863 and r2864.
