Subject: Finally fix SF bug #441172, using a variant of patch ##443626:
X-Git-Tag: v2.2a3~645
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=38507ae614b2b5ef4a888e3b94a3707576021291;p=thirdparty%2FPython%2Fcpython.git

Finally fix SF bug #441172, using a variant of patch ##443626:

The fix takes care to destroy the Entry object, as suggested in the
patch.
