Description Aleksander Trofimowicz 2009-12-04 14:46:46 UTC
abrt 1.0.0 detected a crash.

How to reproduce
-----
1. connect to remote host via TLS
2. try to open vnc console (also nested in TLS)
3. wait for a while (it not deterministic, so you may be lucky enought not to experience a crash)

Comment
-----
remote vnc sessions doesn't work. what is worse, a crash of virt-manager can lead to a crash of virtual machine on a remote host you are trying connect to. host is using qemu-kvm from git tree (head at d0be25...f72848)
using vinagre i have never noticed such problems.

Thank you for reporting this bug.

How reproducable is this problem?  If you run the program from a terminal, is an error message printed?

What version of virt-manager do you have installed?

Looking at the backtrace, it looks like an assertion failed inside frame 2 of thread #1 inside _gcry_ath_mutex_lock.

Reassigning component from "python" to "virt-manager"

i would say the probability is around 0.95 whenever i try to open a graphical console and stick around for a couple of seconds.

yes it is. but there is nothing that cannot be found in the backtrace:

$ virt-manager --no-fork
/usr/share/virt-manager/virtManager/manager.py:150: GtkWarning: gtk_toolbar_set_icon_size: assertion `icon_size != GTK_ICON_SIZE_INVALID' failed
  self.window = gtk.glade.XML(config.get_glade_dir() + "/vmm-manager.glade", "vmm-manager", domain="virt-manager")
python: ath.c:193: _gcry_ath_mutex_lock: Assertion `*lock == ((ath_mutex_t) 0)' failed.
Aborted (core dumped)

0.8.0-7 and 0.8.0-8. both produce the same results.

Comment 4 Daniel Berrangé 2009-12-17 18:21:30 UTC
Needs this libvirt fix

https://www.redhat.com/archives/libvir-list/2009-December/msg00486.html

But also requires a similar patch to gtk-vnc

Comment 5 Dave Torrey 2010-01-08 19:21:40 UTC
To me, this would seem to seriously affect usability, and there appears to be a fix.  Any estimates as to when a new package will be available on the libvirt side?
