segmentation fault when I launch ubuntu-emulator

I have created an instance of ubuntu-touch with QtCreator (Ubuntu utopic armhf in stable version).

When I start it via command line, I had this error :

EDIT : I had read somewhere that this bug was caused by libOpenglRender.so but after renaming /usr/share/android/emulator/out/host/linux-x86/lib/libOpenglRender.so to /usr/share/android/emulator/out/host/linux-x86/lib/libOpenglRender.so.xx the emulator start but it steel blackscreen, even after 10 minutes of booting

If it can help you, this is the Qt log when I try to start it

I really don't understand what's going on !
