Searching the source for the traceback module, I saw that it
calls code in the linecache module which apparently has to
do a manual search down the sys.path to find the files that
are imported...  that probably means (a) there is no other
way to do it, (b) there's example code for you in linecache.py,
and (c) it might have some troubles with the new zip-file
based imports etc... (not that that would be a particular
problem in your case, but it could confuse things).
