I've pushed a few fixes for the coverage module in particular, so you 
should update (and report any *new* problems).

It seems to work fine for me - even with the checker enabled. It is 
possible that one of my recent changes fixed it again :-o Could you try 
it again?

You may want to set the following in the config file if you are using 
the checker as the checker tends to produce a lot of fails!

[debugger]
errors-only = True

Hmm... although if the error or the failure exception is raised inside 
unittest2 code - rather than directly in your code - the debugger plugin 
will drop you into the frame where the exception was raised, and not 
necessarily inside your own code. This is something that could be 
improved. In the meantime you can just type u <enter> to go up frames 
until you return to your code.

The coverage plugins needs more command line options to configure it. 
I'll change the default in the example unittest.cfg to report-html = 
False though.

Hehe, cool but unwise. ;-)

(Thanks for the feedback.)
