you might want to open a separate bug on gtk2-engines-qtcurve, which has the
problem.
In gtk2-engines-qtcurve-1.0.2, common/common.h:1143 we have
double min=QTC_MIN(QTC_MIN(r, g), b),
max=QTC_MAX(QTC_MAX(r, g), b),
delta=max - min;
if max == min then delta is 0 so when we try to divide by it later on, it
crashes. adding a check, something like
if (delta == 0 )
delta=1;
seems to cover this case where r,g and b are all equal, although i've
chosen a value of 1 for delta arbitrarily, the package maintainer will
know if theres a wiser fix.
I've put a 'fixed' package in the ppa below if you want to check it, it works
in gnome using the qtcurve engine, i assume it'll work in kde
