Comment 2 Dave Malcolm 2009-11-13 20:35:19 UTC
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.

Comment 3 Jeff Layton 2009-11-13 20:41:49 UTC
Here's the versions of those two:


...let me know if you need other info.

Comment 4 Cole Robinson 2009-11-15 16:46:16 UTC
Sounds like this is gtk-vnc code, reassigning there.

Comment 6 Daniel Berrangé 2009-12-17 18:42:02 UTC
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
