Thank you for taking the time to report this bug and helping to make Xubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/Xfce. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Upstream has the fix for this in git. Changing the ubuntu to fix-committed to reflect the fix is upstream.
Thank you very much for testing the fix and for helping directly with the xfce developers.
