Open and Save As dialogs don't work

[fuck-shithub]

Pressing Ctrl+O or opening the Open or Save As dialogs makes the screen blink black for one frame and then nothing happens.

I built furnace with cmake .. -DCMAKE_BUILD_TYPE=Release -DSYSTEM_SDL2=ON -DSYSTEM_ZLIB=ON -DSYSTEM_RTMIDI=ON -DSYSTEM_LIBSNDFILE=ON -DSYSTEM_FMT=ON -DSYSTEM_FFTW=ON

I'm using Gentoo with JACK. I use i3 as window manager.

On v0.5.8 it still works but it broke with the v0.6pre1

Update: still doesn't work with regular cmake ..

Okay I think 3be56d5 is the last commit where it still worked

[fuck-shithub]

Yep. 5e77b47 does not compile, and in bfc4432 I cannot open or save as anymore.

It seems that this has been broken since before the addition of vrc6.

Since the addition of vrc6 is important to me, I'll need to see if there's an easy way to produce a patch that includes vrc6 but can also load and save.

Zenity/KDialog must be installed on Linux for the system file picker to work.

I have added an error dialog in case the file picker fails to initialize.
