[Arch] segfault when opening gui

[ExperiBass]

I compiled aqemu without the ppcemb line (#92) and got through the setup before it suddenly segfaulted without a error. i ran it in gdb and got this:

(gdb) backtrace

I got accurately the same problem here with similar trace.

I try to debug this but it's not easy since I'm not a C++/QT dev. I think this problem is related to these warnings:

Finally it was a bad assumption. Everything seems correct in fact.

Here I got a working version if compiled in -j1 else that segfault. But on another system. That don't work either with -j1 so it's confugsing.
