15114	module_has_submodule can report false positives	Michael Shields	nobody	"Python caches failed relative imports using a None in sys.modules.  However, module_has_submodule only checks to see whether a key is present in sys.modules, so it can incorrectly report that a module exists when it doesn't.

Attached is a patch (one line, plus a comment) and a regression test.

The patch is against trunk, but the bug also affects 1.2."		closed	Uncategorized	dev		duplicate			Unreviewed	1	0	0	0	0	0
