Please describe the problem:
The standard FileSaveDialog show some strange behaviour when cklicking on the
'save' button. If the current directory has subfolders the dialog will switch to
the first subfolder when clicking on the 'save' button. A second click on 'save'
will eventually save the file in the subfolder.

Steps to reproduce:
1. Start e.g. gimp from a directory which has subfolders
2. create a new canvas
3. Choose File->SaveAs
4. Enter a filename
5. Click on 'save' 

Actual results:
the current directory will change without the will of the user

Expected results:
the current directory is not supposed to change

Does this happen every time?
yes
