I guess it's not worth it to try to fix doctest/trace to
provide sourcecode for doctest code, but IMHO trace should
be able to survive a doctest.

Removing the assert statement, so that trace.py runs to
completion shows a different problem: There are only
32 files covered according to the trace output. The
complete test log can be found here:
    http://styx.livinglogic.de/~walter/brokentrace.txt

The trace call looked like this:
./python ../../../trace.py --count --summary --missing Lib/test/regrtest.py
with ../../../trace.py being the trace.py from current
CVS with the assert statement removed.

So am I doing something wrong or is trace.py broken?
