This is a by-product of http://code.google.com/p/fbug/issues/detail?id=4203.

We should add a check in to not create a stackframe if the infos are not complete.
Comment 2 Michael Rennie CLA 2011-03-10 12:25:12 EST 
applied a check in CFThreadReference to not create a stackframe if the script infos are not present.
