Reported by: diogo-7
Date: 2014-09-23T17:10:00Z
Status: Fix Released
Importance: High
Launchpad Issue: lp1373037

Using Mixxx 1.12 master branch. When you run Mixxx, before it opens the main window, you go directly to the preferences window, if you don't have an audio interface working.

By this time, if you try to chance Skins, you will get a Segmentation Fault.

Running on:

Linux 3.2.0-4-amd64 #⁠1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux

Here's the traceback:

I'm able to reproduce this. The UI isn't done being set up when we show the sound devices screen, so when the skin changes the fullscreen action has not been initialized. Just moving initActions up above the setupDevices code doesn't work either, because the skin change calls rebootMixxxView, but because setup never finished it fails and the main window never comes up. And the preferences window is gone too.

Is there a good reason not to show the mixxx window before the sound device dialog comes up? It seems like the easiest solution is to push that check until later. Or, pop up a special version of the sound dialog that doesn't let you configure anything else.

I would also just show the mixxx window first and then show the sound device dialog. It is the easiest solution.
