For a few days, a lot of programs do not launch properly. This includes Skype, Oracle VM Virtualbox, Scilab, Boinc, LÖVE, OMG! Words! and a little Java program I downloaded from the web (RemoteDroid). When I launch them from the terminal, I get the same error:
I cannot figure out which is the recent change I made on my computer that is the origin of those errors; is it because I changed my keyboard-layout? Or because I installed a lot of programs for developers?
Notice that it is a general problem, not for just one only application. Moreover, since the two first are closed source, I will not be able to compile them.
