"error return without exception set" when Ice.ImplicitContext not set in IcePy

The exception thrown when getImplicitContext() is called without "Ice.ImplicitContext" set is somewhat confusing. With a blank ICE_CONFIG environment variable:

$ python

}

Thanks for the report. This appears to be a bug in the python plug-in. We'll address it in the next Ice release.
