Subchannel entry crashes the app

on the ccgtv w/ harmony hub, i used to use mac computer dot to enter subchannels when changing channels directly via number entry. now (no idea when this started), it crashes the entire app when doing this. i just submitted logs...has anyone else seen this and is there a way to fix it?

i've also tried mac computer hyphen, that also crashes the entire app.

can anyone else with a harmony confirm that this is happening to them? i submitted logs but haven't heard anything...i can reproduce it every single time, all i need to do is have the harmony send mac computer dot (which previously worked) or hyphen, and the app crashes every time.
