Comment 33 for bug 656241

Considering my previous comment I wonder what the difference is between 'creating' the waveform on startup, and creating the waveform after startup, when enabeling the option from the preferences. The waveform display itselve is not the problem.

Can the workaround be to alwas create the waveform display after the application has been started? So after the ui has been generated check the state of the visuals-option and then decide to draw the waveform area or not?
