Okay, that's actually a good thing because the issue is now isolated
to two similar builds: 0.14.0 from source and 0.14.0 from Ubuntu.

Either there is an environmental difference in the build configuration
or Ubuntu has applied patches on top of vanilla 0.14.0.

I think the next step is to grab the Ubuntu 0.14.0 source package and
rebuild it to confirm that it does *not* have the bug.

Then it's just a matter of figuring out what the difference is by a
(manual) bisection.

Are you using qemu-kvm?  I found Ubuntu's 0.14.0-based package here:
http://packages.ubuntu.com/natty/qemu-kvm
