Comment 2 for bug 988278

It looks little bit more complicated. I tried the following on latest development on Ubuntu 11.10:
1. Open Pinta, create some drawing and save file as e.g. test.png
2. Close file in Pinta: File | Close.
2. Open terminal and change user of this file: sudo chown root:root test.png
3. In terminal change permissions of this file: sudo chmod 700 test.png
4. Open file in Pinta: File | Open, mark the file and click on Open button.

I get the same message: "Could not open file: /home/[my_user]/test.png"

It looks like there are multiple possibilities witch have the same error message.
I think we should be more describing when putting "Could not open file..." message. In this case I would like to see:
1. In bold text something like: You don't have a permission to open this file
2. In normal text it is OK to be written: "Could not open file..."

This now looks more to new feature request.
