When import statements (such as those below) invoke pkg_resources from inside a
file, handled exceptions may be treated as unhandled and break within the debugger.
Because we cannot extract source code from eggs, we will prompt the user to browse to the source file before explaining why they need to do that.
We should not break on exceptions thrown within egg files until they propagate back to user code.
for the better long-term solution.)
