r196 worked on an old pickle, but failed to create a new one.

Sorry for that, I'm in the middle of implementing generators support. I'll get that fixed soon.

I have a problem reproducing this bug. I tried both Python 2.5.1 and 2.5.2 on different modules, with functions with comments, docstrings, or without docstrings and still can't get Pythoscope to fail. Could you narrow the problem down for me? To debug the problem please add the following line:

    print ">>>%r<<<" % unindent(str(code))

Into is_generator_defintion() function in pythoscope/inspector/static.py, right after the try keyword, and before the return line with compile. Then run pythoscope and report the last line of output before the exception. If the code is confidential, please strip it from anything you feel is irrelevant to the issue.

Thank you!

The problem was with functions that had an argument with a default value. Fixed in r202. Thanks for help in catching this bug!
