Expected Results:
No crash

Workaround (if any):

Update: Remove the extraneous trailing comma in the selector list.

OR:

Specify -qualified-type-selectors=true in the compiler arguments.

Will attempt to investigate to discover which .mxml file is open when this crash occurs.
I realize this is not a great bug report without a great repro. I will attempt to repro with Flex 4.5 and will see if I can determine the specific file.
