Gitweb is feeding your input as a perl regex, which is not really clean but shouldn't really harm either.

I could reproduce with an old gitweb version, but newer gitwebs seem to be more clever about regular expression (there's an explicit tickbox to search for re, and the error message is clean when what you provide isn't a valid regexp).
