Here is the expected behavior I expect from ksnapshot:
I do a screenshot, I save it as file1.png, i do another, I cick 'save as' then 'Save' in File Selector, and it is saved as file2.png.

Actual behavior:
1/ I do a screenshot, I save it as file1.png, it do another, I cick 'save as', the  bar is empty, if I click save or press enter, nothing happens.

2/ If i check the option 'automatically selection name and file extension', the location bar stays empty next time, and  
click save or press enter wont do anything either. I have to type file2.png.

3/ If I enter a name without number, like 'test' and click 'Save', it is indeed saved as test, no extension, no number and it is a png. Next Save is not numbered or incremented.

4/ If I uncheck 'automatically selection of name and file extension' (from french menu), and enter 'file' as name, the name is saved as 'file'.

5/ If I uncheck 'automatically selection of name and file extension' (from french menu), and enter 'file1.png' as name, the name is saved as 'file1.png'. Saving next screenshot, when I enter 'file' as a file name, file1.png is proposed in the url bar and the icon file1.png is selected, dismissing the proposed 'file1.png' name and clicking directly 'Save' will result anyway in 'file1.png' being choosen, probably from the icon window selection, and the confirmation dialog to overwrite it appear.

6/ About file type, the automatically select file type deliver a picture of the choosen type ok, but fails to write the correct extension. I understand the extension are not needed in linux and would gladly see them disappear but some other OS need them.

Conclusion: all in all, a regression in usability simplicity wise, I also fail to see any kind of automatisation there so the dialog automatically is puzzling, and a bug in file name selection.

Suggestion: a 'Save Directly' button in ksnapshot under 'Save as' which saves directly to the last used Folder, with the last used name, in the last used type, incremented. It reverts to 'Save as' dialog when used for the first time of this session and when it tries to overwrite an existing file.
