    Description

      When I run `qmlplugindump`, it will most of the time end up in a deadlock. This gets triggered, when I'm building kwin right now (as the build system calls qmlplugindump internally).

       

      Example:

      $ /usr/lib/qt5/bin/qmlplugindump org.kde.plasma.core 2.0

       

      I have attached straces of 3 times where it did not end up with a deadlock, and once where it had the deadlock.

       

      Is there any workaround until this is fixed, like disabling multithreading in qmlplugindump somehow?

      EDIT: we have a workaround in place now for compiling kwin.
