are you telling [gemwin] to stop rendering to create this? (else it
would be weird)

the error does not say very much. probably it is crashing before pd-gui
can show more errors.
try starting pd.com with the "-stderr" flag from the commandline and see
whether you get more errors.
also try to increase the verbosity of Pd by adding "-verbose".

something like:
%PROGRAM_FILES%\pd\bin\pd.com -stderr -verbose -verbose
should do the trick

not really.
anyhow, it would be interesting to know:
- windows version
- Pd version
- Gem version
- camera you are using

finally: try to narrow down the problem, either by going top down
(delete parts of your patch until it doesn't crash any more, and see
which (combination of) object(s) is the culprit) or bottom up (does Gem
work at all after the upgrade? e.g. try the example patches)
