Description of problem: There is a reference leak bug in python-psycopg2. Sadly, I cannot provide narrow reproducer (without Spacewalk components). Version-Release number of selected component (if applicable): python-psycopg2-2.0.14-1.el5 How reproducible: deterministic Steps to Reproduce: 1. Install Spacewalk nightly (PostgreSQL variant) on RHEL5 (or equivalent) 2. Create some non-empty custom channels 3. # /usr/bin/rhn-satellite-exporter --channel=parent-qrywz \ --channel=child-of-parent-qrywz --dir=/tmp/dump.errata.kgCvf28372 Actual results: 02:51:20 Gathering channel info... Appending channels ['child-of-parent-qrywz', 'parent-qrywz'] 02:51:20 Gathering binary RPM info... python: Modules/gcmodule.c:275: visit_decref: Assertion `gc->gc.gc_refs != 0' failed. Aborted Expected results: Export should pass. Additional info:

Created attachment 536653 [details] A proposed patch This problem was actually fixed in upstream. The attached please find an equivalent of upstream's commit: eaa97def731faa6fb9b17cfe9005d327f6a70341
This was observed also on RHEL6 with python-psycopg2-2.0.14-1.el6_2.1
(In reply to comment #3) > This was observed also on RHEL6 with python-psycopg2-2.0.14-1.el6_2.1 Do we have a RHEL 6 version of this bugzilla?
I don't work with the Python CAPI but a quick look at the patch seems sane. I also checked that * This is the only difference between typecast.c in 2.0.14 and typecast.c at the time of the upstream commit. * The patch is still applied in upstream's current 2.4.4 release. Devrim, I'll go ahead and apply and build tomorrow unless I hear otherwise from you.
