The latter. The quit function is called by libgimp whenever the plug-in
quits, not when GIMP quits. This is not very useful, but that is how it
was designed a long time ago.

I am not entirely sure how plug-ins are quit by the core when the GIMP
core exits. It would probably make sense to make sure that the plug-in's
quit function is called. On the other hand we don't want the application
to hang there waiting for plug-ins to quit. If you want to investigate
this further, we could try to help you to fix this issue.
