Not a clue how or when this started happening as I havn't needed to use it for some time.

Here the version and use flags

Code:

[ebuild   R    ] app-emulation/virt-manager-1.3.2::gentoo  USE="debug gtk policykit -gnome-keyring -sasl" LINGUAS="-as -bg -bn_IN -bs -ca -cmn -cs -da -de -en_GB -es -fi -fr -gu -hi -hr -hu -is -it -ja -kn -ko -ml -mr -ms -nb -nl -or -pa -pl -pt -pt_BR -ro -ru -sk -sr -sr@latin -sv -ta -te -tr -uk -vi -zh_CN -zh_TW" PYTHON_TARGETS="python2_7" 0 KiB


Running with debug I received the following

Code:

chris@neuro ~ $ virt-manager --debug

>
Segmentation fault


I've rebuilding but that didn't solve it.

I've tried a debugging with gdb but not sure how to interpret the results.

Code:
