Mist: fatal error: unexpected signal during runtime execution

[hackappcom]

I've cloned go-ethereum on my linuxbox (Linux bright 3.17.2-1-ARCH #1 SMP PREEMPT Thu Oct 30 20:49:39 CET 2014 x86_64 GNU/Linux, go version go1.4 linux/amd64 qt version 5.4.0)

and I try to launch GUI, I get this:

Which version of Qt5 do you have? (this is a known issue with 5.4)

EDIT: Just noticed you do indeed run 5.4

See #212 (comment)

Thanks for your reply.
I've downgraded to 5.3.2 , but here is another problem:

I've just figured out, it was mess with OpenGL drivers, you can read about it here:

https://harishnavnit.wordpress.com/2014/03/06/removing-nvidia-x-drivers-to-solve-the-glx-error/
http://forum.slitaz.org/topic/qt-creator-launch-error
https://bugreports.qt-project.org/browse/QTBUG-34109

On Arch I've just installed (removing all conflicts) mesa driver:

pacman -Sy mesa

My mist system crashed because of the same unexpected 0xb (Segfault) signal. My system also runs qt 5.4.

But following the steps described in your first link, I can confirm that both problems are unrelated. My system correctly initialises the GLX extension of the Nvidia driver.

cat /var/log/Xorg.0.log | grep GLX
2.932 NVIDIA GLX Module 346.35 Sat Jan 10 20:53:39 PST 2015
3.848 Initializing extension GLX

But downgrading to qt 5.3.2 is currently not possible for me.
