When /home is a symlink, for instance (as is often the case on FreeBSD),
group deletion would fail because KConfig was comparing non-canonical
paths with canonical-paths:
QDEBUG : KConfigTest::testDelete() Comparing "/home/adridg/.qttest/config/
kconfigtest_subdir/kconfigtest" and "/usr/home/adridg/.qttest/config/
kconfigtest_subdir/kconfigtest"
