When working simultaneously in different branches, closing of one leads to wrong error message:  I want to shut down several branches of digikam independantly. 

If I click the close button of a window, I do _not_ get the presumably message "do you want to close/shutdown his process", but the (presumably) wrong error-message "do you want to close digikam".

I assume, this to be a minor issue

Reproducible: Always

Steps to Reproduce:
1. just start digikam
2. begin (subsequently) several tasks 
3. try to close one of these

Actual Results:  
If doing so, I get the message "do you want to close digikam" instead of error message referring to the very task. This is misleading info; when working on longs tasks a writing tags, I cannot risk stopping, as I have to fear loosing hours of work...)

Why? I assume this is either a logical mistake the very task would be closed but error-message is wrong, indicating the whole program digikam would be closed.

Maybe the logical dependance between digikam and it tasks does not fit properly

(> closing specific task, message general)

Or, the logic behind is correct, only the message is misleading

Expected Results:  
Very simple:

It must be secured, that closing of a one window of a one task does affect _only_ _this_ very process. Neither misleading info (expressing to stop digikam as a program completely) nor other cross connection between digikam and its tasks
