[Laszlo-dev] ack! completely blank screen, compiling to swf9 with debug=true

[Sarah Allen]

hmmm... I found the bug with the Debug Flash Player installed.

Note, when the bug was there (trying to call a method on a null  
object), when I set
compiler.swf9.catcherrors=true
I got this (unhelpful) compiler error
org.openlaszlo.sc.CompilerError: line unknown: Error: Return value  
must be undefined, in line: }}
line unknown: Error: Return value must be undefined, in line: }}

Not sure if that is worth isolating and reporting as a bug, but it was  
pretty frustrating.  (Debugging was further complicated by having had  
trunk at some point when the debugger had errors in swf9 which was  
fixed by 'svn up' but lost me for a bit)

Thanks for all of your help, Henry & Raju!
