Proposed as a Blocker and Freeze Exception for 29-beta by Fedora user zsun using the blocker tracking app because:
Updating from Fedora 28 will be blocked for lxqt users.
lxqt-themes-0.13.0-5.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-f7fb791026
lxqt is not a release-blocking package set, so this obviously cannot be a blocker. (also note upgrade would likely work with --allowerasing).

Discussed during the 2018-09-04 blocker review meeting: 
The decision to classify this bug as an "AcceptedFreezeException" was made as this prevents upgrades without --allowerasing which can be destructive; it merits an FE to allow upgrades with this package and without updates-testing or --allowerasing to proceed.
lxqt-themes-0.13.0-5.fc29 has been pushed to the Fedora 29 stable repository. If problems still persist, please make note of it in this bug report.
