In dolphin file manager when you have scripts (tested with python scripts (foo.py)), and it has execute permission, __default action is execute__ (left click), so script gets executed. I think this is wrong (I know this can be useful too). In file properties (right click > Properties) there is a 'type' and 'File type options' >> in 'General' everything looks ok, also in 'Embedding', but script gets executed, and for example scripts which expect some user input are "stuck". Probably most scripts downloaded from the internet are saved by default without execute permissions, but still this is somehow a "security problem" too.

For example default options are "respected" in konqueror if used as file manager, they don't get executed.

Reproducible: Always

Steps to Reproduce:
1. create some basic script (python for example)
2. test default action (left click?) on it with and without +x 
3.
Actual Results:  
scripts with execute permission get executed

Expected Results:  
scripts are opened in default text editor (or whatever is set as default action for that file type)
