Indeed it sometimes does, and in those cases you can find a bug by
checking if what Gnash claims is true.

It happens with code like:

if (!a) a = new Object();

which is valid actionscript. But it also happens when coders make a
typing error, when resources used for debugging aren't there in
production code, or when the SWF fails to import resources for any other

So the difficulty is that distinguishing between a genuine coding error,
a bug in Gnash and one of those other cases isn't easily possible. As
the information is sometimes useful (particularly in debugging AS3 at
the moment), it's left there and normally disabled.


Use Gnash, the GNU Flash Player!
