Yep, me too! Thanks for debugging this.

I've applied that fix, and made some other changes (including removing repeated numbers from the drop-down history list). The new version is only on the garage SVN (scm) site as the "gc_dialer.py" file--I haven't tested this on my tablet or built a new deb package yet. Give it a couple of days...

I'm glad to see so much interested in the package, and welcome suggestions...even more, I welcome patches and people who want to work on the code itself.
