[rules-dev] Guvnor problem

[Diablo_UK]

Just done a little bit more digging and it seems that the exception is
occuring when the package is attempted to be read.

If I point a browser at the url, I get the "opening package" dialog from the
browser.  Does this mean that Guvnor hasn't generated the package correctly?

Anyone got *any* ideas?
