No such thing as a GTK server application.

If you have a specific coding problem with PCB, lets discuss that. I'm
not going to dig into threaded programming issues when we don't have to
worry about them. The fact GTK uses threads is an implementation detail
as far as I can see.

I'm not a GTK developer, but I do recall reading / noticing that the
file-chooser backends may launch threads.

Sorry I don't have any more information.
