I finally got it working. Used emerge to build the whole KDE, had some
troubles...

For me it seems like the error was caused from mixing SJLJ unwinding
and DW2 unwinding libraries. I think that emerge (or whatever) uses
DW2, and I had to disable one (prebuilt AFAIK) component in OpenCV
that was using SJLJ one as linking failed. And that
"check_exception_spec" suggests the same origin.
