Crash when using Firefox-Plugin Zim-Clip

Hello,

I am not sure if this is the right place, but I will try anyway.

I am using Zim 0.65 on Kubuntu 14.04 with Firefox 50.0.2 and the Plugin Zim-Clip 0.7.1 .

Often Zim crashes when I try to add content e.g. by highlighting text and then using a right click and "Send to Zim (capture)" from the context menue. I get this error message:

====================================

This is zim 0.65

What should I do?

Thank you very much in advance for your advice!

Best regards
