[Qemu-devel] [Bug 1548170] [NEW] qemu-kvm-spice spice server locks up when large user image is set

[Christopher Snowhill]

Public bug reported:

QEMU emulator version 2.0.0 (Debian 2.0.0+dfsg-2ubuntu1.22), Copyright
(c) 2003-2008 Fabrice Bellard

I have QEMU kvm spice installed, running a Windows 10 1511, freshly
installed this morning, using VirtIO root volume, Ethernet, and QXL
graphics through Spice. It successfully installed the latest updates,
and installed Visual Studio 2010 Professional plus Service Pack 1 and
updates.

Upon attempting to configure the following PNG as my account's user
picture in the Settings control panel applet:

It added successfully, but then I noticed that Windows does not support
alpha blended user pictures, and it blended it against white, so I
quickly replaced it with the following:

Upon assigning that, with the other one still in the previous image
buttons, Spice locked up completely. The VM was still running, as
evidenced by a successful Remote Desktop session.

Do I need to replace my entire Qemu setup with a Git or hand built
official version to verify that this isn't Ubuntu's fault?
