Fails on an individual Kubuntu 18.04 installation

[fxrb]

Since the add-on didn't work on my notebook I installed it in a virtual machine serving as reference. Notbook and VM use the following, identical software:

• Kubuntu 18.04 (64Bit, Plasma 5.12.6, KDE 5.44.0, Qt 5.9.5, Linux Kernel 4.15.0)
• Thunderbird 60.2.1
• MinimizeToTray Reanimated 1.4.4

In the VM the add-on works as expected, no problem at all.

On the notebook I can install the add-on but it does not work. It quite often doesn't even appear in the list of installed add-ons after starting TB. If it does appear, and only then, the menu option Add-ons -> MinimizeToTray Reanimated also appears. However selecting that option does not show the configuration dialog of the add-on; the menu just closes.
I then created a brand new TB profile and installed the add-on but the behavior is the same. The problem therefore doesn't seem to be directly related to a somehow defective TB profile.
Is there anything more I could examine before going the painful (and probably even useless) road of reinstalling TB?

Hi this problem is indeed difficult to understand. You also experience it: Two different behaviors on identical systems.

It is possible that the issue is the same as #18.

You can try this version:
