`get_installed_apps` messes up string offsets
Running following code should show me my installed apps:
require "pebblewatch"
require 'pp'
watch = Pebble::Watch.new("4F92", "/dev/rfcomm0")
watch.connect
pp watch.get_installed_apps
watch.disconnectprints:

The first ones work well, but starting at ID 0 The Strings get all messed up. The app with ID 0 has the name Calendar, but the first char got lost somewhere. Instead the first char of the author field got at the end of the name field (William). As a result, the nullbytes did not get stripped. My guess is, that the offsets got wrong as you still read 32 byte.
Just for the record: ID 4608's name should be "Glow", the author "dotar" I guess. ID 0 (two identical IDs? Maybe something went wrong here, too?) should have the name "Neolog", and the author is me, "Ps0ke". We're two bytes off by now.
Mediabuttons do not work
I am getting no feedback on the media key events. Updating media metadata works just fine, but apart from that I was only able to receive the "Bluetooth discoverable" system message. I am using
% ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
on a Gentoo Linux and an rfcomm device.
My Pebble runs Firmware v1.12.1 and is a V2R2 Hardware. Any suggestions?
