long delay [3-4 seconds] answering incoming calls w/ new 2.17

[meatlocker]

So I hate to revive a dead horse...but I have seen this problem through many ROMs and resets from time to time. I am going through another "Mogul won't answer" phase right now, and just discovered something interesting. If the phone is set to ring (i.e. non-vibrate), I can reproduce the issue. But, if I turn the phone to vibrate, I can answer calls normally with either the answer softkey or the hard button. What the hell? FWIW, I am using No2Chem 5049 right now.
