Exporting perspectives fails with QColor setting

[Kettenhoax]

In ROS humble, when exporting the current perspective via the rqt GUI, while a plugin is instanced that saves a QColor setting, the export fails.

Traceback (most recent call last):

I created a minimal plugin example, that when loaded in rqt can reproduce the issue: https://gist.github.com/Kettenhoax/5e83c83ba2f8887e4fe8da121bd8b367
