"TypeError: read-only buffer, class"

I keep getting this error, please can someone explain what typically causes it?

This is a buglet in ExternalMethod where an exception has been raised and caught by ExternalMethod, and EM is looking at the values of the traceback for some special conditions. It's trying to do a string.lower() call on one of the values that in Python1.4 was always a string, but in Python1.5.x is an instance (in Python 1.5, standard exceptions became classes). This has been fixed and will be in the next release. .jPS | jeffrey@digicool.com zope, through the web. www.zope.org
