Anyway, I did a quick baksmali/smali patch that seems to solve the problem, but I'm not sure if it breaks other functionality. Anyone care to test if it works for them?
ps: this is completely untested, so if it breaks, destroys your phone, breaks into your house and steals your food, I'm not responsible
pps: this routes all audio to the internal speaker, including the ringing sound when someone is calling you!
ppps: I've submitted a bug report to Skype including information on how to fix it, so I'll just wait for them to sort it out the correct way.
