[python-win32] win32com.server failure: Is debugging possible?

[Bob Hood]

I have a situation where I'm using win32com.server to create an in-process 
Explorer shell extension for Windows (7 64-bit).  The extension itself is just 
a sample I pulled from stackoverflow[1].

When I install it, and restart Explorer, opening the context menu on a file 
causes Explorer to crash.  On the other hand, if I install Python and pywin32 
(same versions) into a pristine Windows 7 64-bit VM appliance, and install the 
extension there on an out-of-the-box Explorer, it works perfectly.

Clearly, I have some kind of conflict with the first Explorer instance.  It 
has numerous other extensions installed--Mercurial, Subversion, Directory 
Opus, WinMerge, and on and on.  I'm guessing that I'm colliding somehow with 
one (or more) of these.

Any suggestions as to how I could determine the cause of the crash without 
having to uninstall ALL of my software?
