@Jeremy: your crash is unrelated to this backtrace (yours is related to a binary incompatibility between libplasma and some plasmoid, try to recompile all your plasmoids against the latest libplasma or update all your plasmoids packages)
Thanks for reporting

Changing the report title to avoid more confusions

Any news on this? Have you experienced this crash again with a recent stable KDE version ? Thanks

I guess this is a dupe/related of bug 174787
