Fix format error in claims.

I have now seen two bug reports today about log message formatting
in the claims code. I'm not 100% sure what's going on here, but
I've removed the use of locals() in the hope it makes it clearer.
I've also moved to treating limits as floats because I think it
makes the messages clearer, but it is not a functional change.

Resolves bug 1175923.
