This is the same problem experienced by debian unstable a while back.

See this thread:


The bug was in kst and dealt with the following:

--- quoted from Josh Metzler -----

"Finally, I ran kst under gdb with qt-x11-free-dbg installed and set a 
breakpoint at QPixmap::init just before creating a plot.  After lots of 
continues with valid parameters (w or h is 0 and depth is 0, or depth is 
-1 or 24 on my display), I got one with depth set to 8.  This doesn't 
cause a problem here because w = h = 0, so a null pixmap of depth 8 is 
created.  When it is resized, however, it causes a problem.  With the old 
qt behavior, an invalid depth was ignored when creating a null pixmap.

So, the bug is in lines 84, 124, 389 of kst/kst/kst2dplot.cpp where it 
specifies a depth of 8 when creating the KstBackBuffer.  It should 
probably use the default of -1 and let qt create a QPixmap of the 
appropriate bit depth."

So, not sure if this is related.  For what it's worth, I'm using KDE 3.5.1 and 
Qt 3.3.4 on Kubuntu without problems.
