Created attachment 234021 [details] stack trace
Downgraded libvirt and libvirt-python to version 0.2.2-4 and everything start to work again.
Stack trace is unfortunately unusable, there is no symbols: ------------------------ /lib/i686/nosegneg/libc.so.6[0x3419b1] /lib/i686/nosegneg/libc.so.6(cfree+0x90)[0x345060] /usr/lib/libvirt.so.0[0x46885e] /usr/lib/libvirt.so.0[0x46a07b] /usr/lib/libvirt.so.0[0x4419d3] -------------------------- install the debuginfo packages to provide more details. The daemon was renamed between 0.2.x and 0.3.x are you sure you properly sutdown the libvirt daemon before the upgrade (or downgrade) amd restarted it after ? Still that should not crash, what platform (i686/x86_64) are you using ? Daniel

I've attached GDB backtrace and my /proc/cpuinfo. I've installed i386 Fedora as shown in this bug "hardware" field, but my CPU is Intel EM64T as you can see in attached cpuinfo.
