It doesn't like the new line you suggest. Compile errors are below. It does like Doug Scoular's suggestion to put it back to the way it was in 0.17.

I think we are making some progress now :-) It looks like we're exposing a bug in the kde3.2.x version of KCmdLineArgs to me. I use 3.3.0 and 3.3.1 and it works fine. I changed the call to KCmdLineArgs::init because the old call kept producing a compiler warning about 'init' is deprecated or something similar. Because I can't reproduce the problem here it is not possible for me to debug it. If you have the time there is a few things you could try to track the problem down. Its a long shot but I wonder if the compiler is getting confused about which init call to use. Though I can't see how that could be. Could you try changing it to this and try again.:- KCmdLineArgs::init(argc, argv, "mythbrowser", "mythbrowser", usage, version, false); That should remove any ambiguity about which call to use for the compiler. Another thing I noticed looking at the code is the order in which the arguments are parsed and the creation of the KApplication object looks back to front to me. Move 'KApplication a(argc, argv)' to just after 'KCmdLineArgs::addCmdLineOptions(options)' and before KCmdLineArgs * args = KCmdLineArgs::parsedArgs(); so it looks something like this:- KCmdLineArgs::init(argc, argv, "mythbrowser", "mythbrowser", usage, version, false); KCmdLineArgs::addCmdLineOptions(options); KApplication a(argc, argv); KCmdLineArgs *args = KCmdLineArgs::parsedArgs(); That looks more like the example code in the KDE docs. In fact I don't think we need to pass the arguments to KApplication at all and just replace KApplication a(argc, argv) with KApplication a; Thanks for your time.
