The crash is in the nouveau video drivers. Please report this issue directly to nouveau developers via https://bugs.freedesktop.org/
Comment 2 Nelson Fonseca 2017-01-11 03:12:18 UTC 
Hi Christoph, good day,

Yes, I could confirm this case as RESOLVED, the problem was the nouveau driver, 
I remove this video driver and installed that one from nvidia and the problem 
is completely gone, at this moment I am writing this message from Kontact with 
no error at all.

So, I could conclude that I am not going to use this OpenSource driver anymore 
instead to use nvidia.

Thanks a lot for your support.
