Subject: [PATCH] python: return None if PY_IMPORT_STRING returns NULL
|
|
|
|
PY_IMPORT_STRING might return NULL on python 3 if, ie, a string can't be
|
|
encoded. We should check for this and return None, rather than returning
|
|
NULL. Fixes a NULL pointer dereference when reporting an error with an
|
|
invalid string.
