Image is not visible on folder

Hi

I have a freak problem
I can’t import image in my project because the image is not visible in folder

The strange thing is that is yesterday this problem did not exist

This is a bug?

Here have a short video in which I show the problem

I use ubuntu 15.04

Hi

I found an freak solution for my problem (certainly this is a bug)
I need drag my image from my folder inside GDevelop
Take a look my video
Is complete crazy

Seems more like a bug in GTK or in wxWidgets, the lib used by GDevelop to show a GUI.
