Dolphin displays thumbnails of files, even if you do not have read access to these files.
I set the severity of this bug to "major" because there is a security issue : the content of a file that is not readable mustn't be displayed.

STEPS TO REPRODUCE
1. Create a file "a.jpg" and display its thumbnail in Dolphin
2. chmod 0 a.jpg
3. Refresh Dolphin display (or even quit Dolphin and restart it)

OBSERVED RESULT
The thumbnail of a.jpg is still displayed (although you have no right to see the content of the file).

EXPECTED RESULT
No thumbnail should be displayed for files you are not allowed to read.
