Of course I agree.
Still I thought it will be nice to know when I am dealing with situations 
unlikely to fail and when with such *highly* likely to fail.
I need fastest possible open, so I thought to use less caution approach for 
files on the machine disk and be much more caution for files over the network 
(even redirect them to QNetworkAccesManager completely for handling).

I will not argue if this is The Right Thing, I am just considering options.
