Well, after all that whining it appears to be not so dire. I simply
commented out the call to getFrameArgs() and that got me all the way to
setting up a simple bug session! I'm stepping thru code and printing
variables in rdebug. Woot!!
Martin, can you give me some insight on what getArgc in DebugFrame is used
for? I couldn't find any references to it. This is the only thing that was
using getFrameArgs()
