[Pkg-libvirt-maintainers] Bug#563120: libvirt-bin: libvirtd segfaults when trying to connect to it with malformed connction URIs

[Mateusz Kijowski]

Package: libvirt-bin
Version: 0.7.4-2
Severity: important


When I try to connect to libvirt using:

virsh --connect qemu://

libvirtd process crashes with SIGSEGV:

Program received signal SIGSEGV, Segmentation fault.

#8  0x0000000000000000 in ?? ()

The backtrace is propably not useful, but I can't find any package containing
debug symbols for libvirtd. I have libvirt0-dbg installed, but it doesn't
seem to have the symbols for libvirtd and there is no libvirt-bin-dbg package
I could find.

When trying to connect with proper URI, that is:

virsh --connect qemu:///system

everything seems to be fine.
