Well, this seems to be a bug then.

OK, here is what I did. I used a fresh KDevelop from SVN (today). I had all my 
config files about kdevelop removed (rm -rf /home/tmg/.kde/share/apps/kdev*; 
rm -rf /home/tmg/.kde/share/config/kdev*)

1. Start KDevelop
2. Project->Import Existing Project...
3. Project type: Qt4 C++ Application (QMake4 based)
4. Select [..]/qt-copy/examples/dialogs/findfiles as directory
5. Click OK, then QMake Manager
6. Click on window.cpp
7. Place a breakpoint at line 68 (View-Show line numbers), which is the first 
line in Window::browse()
8. Debug->Start. Click yes when asked to rebuild project
9. In the app, click browse
10. The messagebox should be shown now (twice!)

Note that I am doing all this as the regular user, e.g. the KDE3 + QT3 user.
My qt-copy is located in the home dir of my kdedev user. Since I am the 
regular user, no KDE4/QT4 env vars are set at all.

11. Type asdf in the lineedit of the Variables widgets, and hit Watch.
9 (!!) Error boxes are shown now.

Also note that I can not remove asdf from the list of watched variables, since 
it is grayed out.This makes the asdf message box appear every time i step.

Maybe you should rething what I said about not showing these error boxes.

As Hamish noted, this happens only when the Qt options are set to Qt3, which 
seems to be the default after importing a Qt4 project.
I wonder why I haven't noticed before that my Qt settings are wrong, but 
nevertheless these message boxes should die.
