variety crashed during open a file in Terminal (betty)

Hello to all,

at 1st I use UBUNTU 16.04 and variety and a lot of other stuff.
So, my two problems are :

1st when I open a Terminal and in the terminal I start a file "betty" and in that program, when I write
that line betty turn web on, variety crashes every time I do this, this fault happens also, when I start
variety manually.

2nd when I open variety and I'll go in preferences / settings and when I want delete some pictures,
variety shows up a error. So, when I want to delete a lot of pictures, I let the error on, after I
finished with the deleting of the pictures. I press that button, where the error is shown up, and variety
restarts and all is fine, but after approximately 1 or 2 hours it crashed complete, so I must restart
it manually. My question is :

Has anyone of you the same trouble with variety, or I'm the only one ?
