I think I found the reason.

In ~/.nx/C-hetzner-1000-22AE0F86E0840D789E91259774162098/session, there's:

nxclient.bin: error while loading shared libraries: /usr/NX/lib/libXcompext.so.1: cannot make segment writable for relocation: Permission denied

This line gets added, when I try to quit the application.

I should mention that I'm using a hardened kernel on the Gentoo host.

On http://www.gentoo.org/proj/en/hardened/hardenedfaq.xml#paxnoelf I find:

What executable is using the non-PIC library /usr/NX/lib/libXcompext.so.1?
