Description of problem: I see this crash every time I try to start any VM from virt-manager. It immediately crashes. However, I can connect to that VM using virt-viewer afterwards. I can also control my VMs using virsh. The problem seems to be related only to virt-manager. Version-Release number of selected component: virt-manager-1.4.0-3.fc24 Additional info: reporter: libreport-2.7.2 backtrace_rating: 3 cmdline: /usr/bin/python2 /usr/share/virt-manager/virt-manager crash_function: in executable: /usr/bin/python2.7 global_pid: 6101 kernel: 4.6.4-301.fc24.x86_64 pkg_fingerprint: 73BD E983 81B4 6521 pkg_vendor: Fedora Project runlevel: N 5 type: CCpp uid: 1000 Truncated backtrace: Thread no. 0 (10 frames) #2 0x00007f096ce12acb in #3 avcodec_alloc_context3 #4 gst_ffmpeg_cfg_install_property at gstavcfg.c:732 #5 gst_ffmpegvidenc_class_init at gstavvidenc.c:225 #6 g_type_class_ref at gtype.c:2241 #8 gst_element_register at gstelementfactory.c:243 #9 gst_ffmpegvidenc_register at gstavvidenc.c:1009 #10 plugin_init at gstav.c:158 #11 gst_plugin_register_func at gstplugin.c:523 #12 _priv_gst_plugin_load_file_for_registry at gstplugin.c:826

I removed ffmpeg and it stopped crashing. Then I installed it back and it was still not crashing. I rebooted and it wasn't crashing. So I have the same system state as before, but it's not crashing now, I can't reproduce the problem. I ... don't know.
