Without any logs or errors there is nothing we can do

I've attached the kcrash log file.
I hope it is useful.

is your home partition mounted with noexec?
Comment by Simon (Giggi) - Monday, 30 January 2017, 17:37 GMT
No.
It is mounted normally:

That's my entries for the root and home partitions:
UUID=43ffcf60-0458-49f7-a537-2bce90817e9e / ext4 rw,noatime,discard,data=ordered 0 1
UUID=df5f3cab-1647-4ce8-a725-13b92b664476 /home xfs rw,noatime,attr2,discard,inode64,noquota 0 2

Can you please try:

cp /bin/uname ~/.cache/ && ~/.cache/uname

> cp /bin/uname ~/.cache/ && ~/.cache/uname
> bash: /home/sim/.cache/uname: Permission denied

Same result also if I a try with "sudo"

Another note:
Before the crash of the login procedure it appear the mouse pointer (icon) that normally I use with KDE.

I'm using an Nvidia video-card with the related driver (nvidia)

In the /var/log/Xorg.0.log I've seen this suspect message ....

Well, there's your problem. Find out why you don't have execute permissions for ~/.cache
As a workaround, set the env variable QML_DISABLE_DISK_CACHE to 1
