"Can't find program" exceptions are shown in an ugly way · Issue #23 · nedbat/coveragepy (original) (raw)

If you use "coverage run xyzzy.py" and xyzzy.py isn't found, the exception shows stack frames from coverage.py itself:

C:\ned\coverage\trunk> coverage run xyzzy.py
Traceback (most recent call last):
