Could you please retest. I backported an upstream change, which fixed it for me. + 13 Mar 2012; Justin Lecher <jlec@gentoo.org> i7z-0.27-r1.ebuild: + backport upstream addition to CXXFLAGS, #407881 +
Confirm the fix makes i7z_GUI usable (does not crash anymore). But while looking into the GUI-Code, I found one possible problem: MyThread-Members are set in run() (so in another Thread then the GUI-Thread (mainthread)), and read from the GUI-thread in UpdateWidget - all without locking. So if i7z_GUI starts behaving strange, this could be one possible source. I first thought this would have caused the issues, that are now solved.
Maybe I just added an work around. Please post you findings to the upstream bug.
