As I said on IRC, there is a suppression for this leak in upstream but it didn't work because
by 0x364663D0E4: ??? (in /usr/lib64/libssl.so.1.0.0)
is not resolved, which probably depends on distro/openssl version or smth.
I propose we just make this suppression work.

Either an upstream bug as-is, either a bug that is benign on upstream but visible on PS due to different SSL library used.

Actually, not qablock/critical. But may be easy to fix in one patch with bug 1191582.

This is a split from bug 1191582. Testing for this error can be done with the testcase from that bug (note to self: /sssd/209184/start_mtr1000). If you like, we can test a fix in the same bug branch used for that bug.
