Plasma segmentation fault

Using a ruby plasmoid with a recent build of qtruby crashes
plasma/plasmoidviewer. I regenerated/recompiled from scratch
smoke/qtruby/korundum/plasma.

I'm not sure what is causing this as nothing much has been changed recently.
Does it crash with any Ruby plasmoid, or just some?

Every tested plasmoid, stealth-cashew, isohunt, ruby-extender-tutorial,
crashes. Only ruby-extender-tutorial does appear, because it does not do much
initially. Once a job starts, it crashes too.

Disabling GC does not help.

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:
