Description

With strace, it is visible that Qt (installed in /usr/lib64) tries to load a plugin relative to the current directory:

~> strace -fefile qdbusviewer |& grep -i hasw
[pid  3055] openat(AT_FDCWD, "haswell/libXcursor.so.1", O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
[pid  3055] openat(AT_FDCWD, "haswell/libXcursor", O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)

This is undesirable as the CWD contents can be unknown, so it might be finding something which it's not supposed to.
