Comment 1 David Jaša 2012-10-17 14:46:18 UTC 
forgot to add (for both revisions the same):

Core was generated by `remote-viewer --spice-controller'.
Program terminated with signal 11, Segmentation fault.

Comment 2 David Jaša 2012-10-17 14:47:19 UTC 
virt-viewer-0.5.2-11.el6.x86_64 works fine, everything else being equal.
Comment 3 Marc-Andre Lureau 2012-10-17 19:03:23 UTC 
danpb, please cherry-pick cc0696f46f99055c042b47f3a36477719dc2580d

We currently block on you for package update, if I understand correctly.

Comment 7 Geyang Kong 2012-10-26 10:41:59 UTC 
Verified pass on the following build:
virt-viewer-0.5.2-16.el6

Can be reproduced by following build:
virt-viewer-0.5.2-14.el6

Reproduce steps:
1. Install spice-xpi
2. Have a spice guest on RHEVM.
3. Try to launch remote-viewer through RHEVM web page.

Actual:
1. Remote-viewer launched normally and stayed operational.

So mark this bug as VERIFIED.
