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"

Needs this libvirt fix https://www.redhat.com/archives/libvir-list/2009-December/msg00486.html But also requires a similar patch to gtk-vnc https://bugzilla.redhat.com/show_bug.cgi?id=537489
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?

The -16 patch definitely solved this problem for me. I could reproduce it consistently and I cannot any longer.
