Which gtk theme/theme engine do you use for GTK2 applications?

Based on the described symptoms (there is no actual information provided, e.g. a backtrace which would allow to further investigate) this crash seems very similar to the ones about a crash in qtcurve reported earlier by other KDE users:
* Bug #1422479 “Crash under Plasma5 an qtcurve”
* Bug #1463877 “Inkscape crash on color palettes hover (qtcurve).”
* Bug #1469727 “Crash on GTK widget creation after save (qtcurve)”

Thanks for your answer.
I was using QTcurve but now Oxygen-GTK, I will see if it's better.
