They are telling everybody that we are using the Gtk in a wrong way, but the correct way is not really documented anywhere.

As my branch is not using Gdk locks at all, it is meaningless now. I actually used @gtk_thread_wait for the two dialogs from UserInterface and exception.py uses idle_add so it should be OK as well. > > I am testing those changes (including the infamous lockup when removing last keyboard layout :), but it takes long time as you can imagine. We also have to take a look at python-meh with Vrata to make sure everything plays well together. Running 'kill -USR1 `cat /var/run/anaconda.pid`' should be good for testing as it raises an exception from a separate thread. -- Vratislav Podzimek Anaconda Rider | Red Hat, Inc. | Brno - Czech Republic _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
