lxqt-panel-0.13.0-3.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-4867c38838
Discussed during the 2018-09-04 blocker review meeting: 
The decision to classify this bug as an "AcceptedFreezeException" was made as this issue affects one of our live images and cannot be resolved with an update, the fix is clearly limited to lxqt only, and it cannot break anything else.
lxqt-panel-0.13.0-3.fc29 has been pushed to the Fedora 29 stable repository. If problems still persist, please make note of it in this bug report.
