Freeze on opening colour selector.

[Timmy1e]

The application always freezes on opening the colour selector. Output, after this it freezes:

I'm on Linux 4.8.4-1-ARCH x86_64, running ckb-git-latest: v0.2.6.r34.g34cd4c8-1.

Under the AUR comments:

I also had to install qt5ct to be able to change colors and avoid the critical error: "GLib-GObject-CRITICAL **: g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed"

This fixed the issue for me as well, running 0.2.6 as well.
