You need to construct your geo: URL properly. See the documentation for the syntax. I think you may only be missing a q between the ? and the =, but I have not tried that particular geo: syntax.

Make sure that you are using the Google API emulator image for your testing. Bring up the AVD and set the emulator to be a Google API emulator. If you don't do this, then you will continue to get the bug. Also, the previous poster was right... you need to following the URI standards found here: http://developer.android.com/intl/de/guide/appendix/g-app-intents.html
