[Kst] Valgrind of current trunk shows errors/leaks...

Hi all,
Using valgrind to debug a problem in my branch, I found the some further
problems in trunk. Valgrind is reporting three errors and seven leaks in
trunk. I've fixed one of the errors in my branch where a conditional was
dependent on a potentially uninitialized value. I've attached the patch.
Another error involves the VectorSelector widget displaying a pixmap from
QImage. The last error involves ICE via dcop I presume. The leaks all seem
to involve either X or the Qt libraries. This is on SuSE 10.0 with the
standard libraries shipped by this distribution. Valgrind version =
valgrind-3.2.0 installed from source.
Cheers,
Adam
