[Zope-dev] zope.testing.testrunner.find.find_suites molests exc_info

      Hi Christian,

In trying to debug this:

TypeError: If post_mortem is specified, full exc_info must be passed!
...I discovered that the exc_info is being cut to bits in find_suites:

except:
     suite = StartUpFailure(
         options, module_name, sys.exc_info()[:2]+(None,))

...which svn blame attributes to you. Any idea why this is being done?

Changing the above to:

                         suite = StartUpFailure(
                             options, module_name, sys.exc_info())

...appears to have no effect other than making post mortem debugging 
work and actually showing the traceback when the exception occurs, which 
both seem like a good thing to me.

Can you or anyone else shed some light on this?

Chris
