+ testqtargs -- is there really a bug in KCmdLineArgs or am I on crack?
+
+  I used the following compile options:
+
+  g++ -g -Wall -o testqtargs testqtargs.cpp  -I/usr/X11R6/include \
+  -I/opt/qt3/include -I/opt/kde3/include -L/usr/X11R6/lib -L/opt/qt3/lib \
+  -L/opt/kde3/lib -lqt -lkdecore
+
+  if invoked like this ./testqtargs --bg blue --caption something --hello hi
+
+  The program should list argv[] then produce output like this:
+  
+  qt arg[0] = background
+  qt arg[1] = blue
+  arg bg = blue
+  arg caption = something
+  arg hello = hi
+
+  Instead for me it prints:
+
+  qt arg[0] = -background
+  qt arg[1] = blue
+  arg caption = something
+  arg hello = hi
+
+  See the extra dash in qt arg[0]?  I believe that is the cause of the problem.
+  --bg is aliased to --background but If you try it with --background or 
+  -background, you get the same thing.
+
+  in kdecore/kapplication.cpp, KCmdLineOption qt_options is defined and used 
+  by the static method Kapplication::addCmdLineOptions to add the Qt options
+  but its' entries look like this:
+
+  { "background <color>", I18N_NOOP("sets the default background color and an\n
+application palette (light and dark shades are\ncalculated)."), 0},
+
+  it looks for "background"  instead of "-background" so never find the arg.
+
+  Software:  g++ 2.95, kdelibs from CVS Jan 28, Qt 3.01
+  OS: Debian GNU/Linux 3.0 (sid)
