New to list, make in applet

[David Baron]

I am building an applet to control a speakerphone modem. I have encountered 
the following problems:

1. As per another post,  I cannot use icons from the qt framework. A 
setIcon(QIcon.... to a qt control or setIcon(KIcon ....) is a sure crash out. 
Setting Icons in the qt designer uses qPixmap routines. Where might I find 
these and reference them in  a cmake?

2. popupPosition() places the widget horizontally with the applet but high up 
on the screen.

3. The applet, widgt high up and sans icons, works nicely. Plasma will crash 
on the next login (there is a lot of that going around, it seems). I suspect 
nvidia but have no idea.

The only clue is that if I use it in the viewer, things are just fine for 
quite a while and then plasma MAY crash. Here is a small part of the very 
lengthy dump:

On the startup crash, no usable dump is produced.

Any ideas?
