[Comment from a bug triager]
The crash could be cause by some error in the Qt library, or a bug with the NVIdia drivers (very likely). It is known that some versions of the NVidia driver caused a lot of random bugs. Try to update it frequently.
If you experience another Plasma crash please open a new report.
Thanks
