Thanks for the bug report. All the needed details are here, so I've forwarded this bug upstream.

[Mario Limonciello (superm1)]

As this is now fixed in an upstream build that should be included with autobuilds, i'm going to close this bug. Upstream committed it to trunk, so if you'd like to see it in -fixes, you can discuss with them backporting it.
