Mail.app: Control-T key combination causes instant quit without warning

As first noted by MacFixit reader Jean-Denis Muys and confirmed in-house, entering the keyboard command "Control-T" when composing a message (with the cursor in the message text field) in Mail.app will cause an immediate quit without warning.

Jean-Denis writes:

"When typing a new mail in Apple Mail version 2.03 (734) under MacOS X 10.4.2 (build 8C46), if I inadvertently push down the Control key and I happen to type a 'T', then Mail suddenly and immediately quits, without any warning, nor any system crash report.

"Unfortunately, this happens quite frequently, because on the Apple white keyboard, the Control key is at the bottom left corner, and the palm of my left hand often pushes the control key down. Since I type rather fast, very soon the 'T' letter is likely to be pressed and 'Boom'...

"Needless, this is infuriating because the mail I was typing is lost, and you have to type it again."

The "Control-T" keyboard combination is used in some text editors (like BBEdit) to invert letter ordering.

We've yet to discover a viable workaround for this issue.
