Can you please be so kind as to supply for helpful information, such as the things you were doing to make Kdenlive crash and an example project showing the crash? Or does Kdenlive crash at startup? Also, please be so kind as to use a bug report title that can be understood in general by others, English is the common language to be used here.

I cannot reproduce your crash on Kubuntu 16.04.1. This may be a packager issue of Ubuntu.

Please try with the latest stable 16.04.2 or recent beta from Kdenlive's own ppa's for reference. Please report back either success or failure.
