I dont really know what is happening on your system, it works nicely on mine, 
but from annotating the backttrace we may get an idea

Read from bottom to top:

#6  0xb60b44a6 in QWidget::topLevelWidget ()
   from /usr/lib/qt3/lib/libqt-mt.so.3

...leads to querying the topLevelWidget, which is probably the dialog, which 
is destroyed by now, or at least at the end of its destructor

#7  0xb6e39ce3 in KParts::StatusBarExtension::statusBar ()
   from /opt/kde3/lib/libkparts.so.2

querying the status bar object...

#8  0xb6e4862f in KParts::StatusBarExtension::removeStatusBarItem ()
   from /opt/kde3/lib/libkparts.so.2
#9  0xb75e1327 in KHTMLPart::removeJSErrorExtension ()
   from /opt/kde3/lib/libkhtml.so.4

Now it tries to remove some widget it put in the status bar

#10 0xb7629a25 in KHTMLPart::~KHTMLPart () from /opt/kde3/lib/libkhtml.so.4

base class destructor

#11 0xb3057725 in ~GPSMapWidget (this=0x8931150) at gpsmapwidget.cpp:74

I think GPSMapWidget inherits KHTMLPart? In fact, it is destroyed now from 
KParts code, as reaction to destruction of the dialog

#12 0xb6e3f657 in KParts::Part::slotWidgetDestroyed ()
   from /opt/kde3/lib/libkparts.so.2

which is connected to slotWidgetDestroyed() from KParts code

This is the code for the Ok button, closing and destroying the dialog
