Emulsion panics immediately at start

[raphCode]

I get the following backtrace when trying to open the application on Arch Linux with X11. The Emulsion window shows up for a split second, but without any content (no X drawcalls, the background window content is displayed). The window title reads "Loading".

This is an Intel Atom D2550 CPU with integrated graphics that are not supported on Linux.

It happens also when trying to open an image. I used the code from the 9.0 release.
