Strace is usually useless for crashes. Please provide a backtrace from the crash (http://wiki.documentfoundation.org/BugReport#How_to_get_backtrace_.28on_Linux.29).

The bug is in the style. Function PolyesterStyle::drawComplexControl() dereferences the widget pointer argument in the CC_ToolButton case even though Qt documentation says the argument is optional and can therefore be NULL. You'll need to report to the style developers.
