Weird Hardware Key Bug

[menoats]

I was just wondering if anyone else has had this bug and if so does a fix exist.

When I attach the headphones that came with the phone, then play a song, and press the power button to turn the screen off. The hardware keys stop responding.

The touch screen still reacts but the hardware keys no longer function and there is nothing I can do. Not even the fold out keyboard responds and I can recreate this bug everytime. Really annoying. Considering its common sense to turn off the screen after you select your music to save battery time. Does anyone else have this issue?
