LR 4.1 internal error for GPS coordinates

With the 4.1 upgrade today, the metadata panel no longer accepts GPS coordinates I use of the form "29.713669,-95.404193" (without quotes). It results in "An internal error has occurred. bad argument #1 to 'trimWhitespace' (string expected, got number)" Needs immediate correction, my images are out-of-compliance with CBS and Associated Press guidelines and have to be edited in another program. Did you regression-test this?
