This fail is almost comedic.. type=AVC msg=audit(1238718282.630:12255): avc: denied { execmem } for pid=8305 comm="setroubleshootd" scontext=system_u:system_r:setroubleshootd_t:s0-s0:c0.c1023 tcontext=system_u:system_r:setroubleshootd_t:s0-s0:c0.c1023 tclass=process This AVC triggers setroubleshoot to then start up, and oops.. Another AVC, which causes...
there's a gazillion msgs in dmesg like .. setroubleshootd[8604] general protection ip:7f024265790d sp:7fff4ab85c00 error:0 in libpython2.6.so.1.0[7f02425be000+169000] which is likely related.
haven't seen this happen since I did a complete relabel. red herring?
There were other problems causing the libpython crash (libselinux) and the execmem (nss). So both should be fixed in rawhide.
