[Twisted-Python] disturbing trial exceptions

[Markus Schiltknecht]

Hi,

since my last svn update of twisted, some strange errors started popping 
up when testing my package with trial. I've tracked down the exact 
revision with which the errors started to appear:

> ------------------------------------------------------------------------

> but create temporary plugins beneath _trial_temp instead.
> 
> ------------------------------------------------------------------------

The first exception is:
   exceptions.AttributeError: 'module' object has no attribute 'running'

As the errors are from seemingly dynamically generated code (at least I 
could only find .pyc files, no source), I didn't try to investigate further.

After the errors, all tests are correctly run through, so it's just 
plain disturbing.

Here's the full error output:

Help appreciated.
