[3dprinter-general] Bug#950919: Bug#950919: cura: unable to remove annoying popup message

[Ernesto Alfonso]

Is there a short term workaround you can suggest? I tried searching for the
error message in the debian package sources, something like "Re-installing
the plugin" or "plugin.*could not be loaded" but couldn't find anything.
