Assertion failure in _gcry_ath_mutex_lock
Last modified: 2014-06-18 03:39:28 EDT
abrt detected a crash.
Comment: Trying to open a console in virt-manager of a machine on another host.
Attached file: backtrace
cmdline: python /usr/share/virt-manager/virt-manager.py
reason: Process was terminated by signal 6
Created attachment 369479 [details]
Thanks for filing this bug.
From the backtrace, it looks like an assertion failed; frame 2 of thread 1 has:
Assertion `*lock == ((ath_mutex_t) 0)' failed.
in _gcry_ath_mutex_lock, deep inside gvnc_start_tls (frame 21) within gvnc_initialize (frame 24).
So it looks like an assertion failure deep inside gvnc's TLS code, which causes the process to abort.
Reassigning component from "python" to "virt-manager" in the hope that someone with knowledge of that domain can assign it to a more appropriate component.
He or she will probably want to know which version of virt-manager, libvirt, etc you have installed.
Here's the versions of those two:
...let me know if you need other info.
Sounds like this is gtk-vnc code, reassigning there.

Fix built in gtk-vnc-0.3.10-2.fc12
This fixes the problem as far as GTK-VNC is concerned. It'll likely still crash though because of an identical bug in libvirt https://bugzilla.redhat.com/show_bug.cgi?id=544305
