I can't reproduce this problem here anymore - the two segfaults i knew of are both solved in latest gnome-vfs & gtk RPMs from about a week ago. Could you try and capture a stack trace for the crash. You'll need to do something like this: # yum --enablerepo=development-debuginfo install python-debuginfo, gtk2-debuginfo & virt-manager-debuginfo # ulimit -c unlimited # virt-manager # gdb /usr/bin/python core.XYZ Created attachment 137232 [details]
requested backtrace attached
fc6t3 + all updates till sep 27th 13:00 EDT
Thanks for the stack trace. I'm investigating the problem & have a couple of leads which look promsing.... Committed two fixes to upstream repo for this issue http://hg.et.redhat.com/virt/applications/virt-manager--devel?cs=bf53891faa22 http://hg.et.redhat.com/virt/applications/virt-manager--devel?cs=1cb01dfe5d34 Will add patches these to next RAWHIDE update of virt-manager. i was going to write that not only does it no longer segfault - it now just exits silently - but that is because i wasn't running xen on my host... (which would be a nice message after clicking "Connect") still - i now have virt-manager-0.2.3-1.fc6 - and it still segfaults. will attach backtrace. Created attachment 137448 [details]
similar backtrace for newer version.
The fix was not in version 0.2.3-1.fc6, but I have just built a version 0.2.3-2.fc6 which will have the neccessary fix. The reason it is a sporadic failure is because it is based on a subtle timing issue which causes the calculated CPU utilization to go a little over 100%, which break sthe sparkline validation, in turn resulting in a null data set which then makes the rendering code SEGVs. Anyway, check out 0.2.3-2.fc6 once it hits rawhide (hopefully tomorrow). *** Bug 208916 has been marked as a duplicate of this bug. *** Closing on the basis that bug 208916 showing the same problem has reported 0.2.3-2.fc6 fixes the issue. yep sorry about that - confirmed fix with the release mentioned. thank you. |
