- Do you know which engine(language) does this widget use ? It could be a bindings error or a bug in the widget itself.
Thanks

I can not tell, but ist is the widget installed via widget explorer, which are hosted on kde-apps.org (I think). The crash also occurs when I put the widget on the desktop. There I can read "script initialization failed". Shortly after -> crash.

Here the trace back
