Comment (by gk):

 gacar: thanks. One question: Why do you have
 {{{
 JS::DescribeScriptedCaller(aCx, &scriptFile, &scriptLine)
 }}}
 wrapped in an if-clause? Reading the code this means to me this call can
 fail but *not* for
 third-party content as you are assuming `scriptFile.get()` and
 `scriptLine` are available unconditionally in this scenario. If that is
 correct which failing scenarios did you have in mind?

 mcs: you have the merge power, too, now ;)
