looks like a corrupted library, using strace to find out which one it is. Somehow in the strace output you will properly find something like that  -1 ENOENT (No such file or directory)
depending on your line limit in your terminal, best is to pipe the strace output into a file,

strace jalv.gtk http://guitarix.sourceforge.net/plugins/gx_amp#GUITARIX | > stracejalv.txt

  what():  

due to the new retina display I've installed both KDE and GNOME. I wonder if the problems com from that.

I wouldn't believe that this will have a influence at all.

Any help is appreciated.

kind regards
