[Kde-bindings] Plasma segmentation fault

Sun Nov 1 19:05:53 UTC 2009

The ruby-extender-tutorial backtrace is different. But when I use the
'applicationjobs' data engine from a korundum program it crashes because
Smoke can not handle DataEngine::Data.

Backtrace with plasmoidviewer:

Application: Visor de componentes de plasma (plasmoidviewer), signal:
