We've found that 2.5 is URLencoding image filenames - in particular, turning spaces into %20 both in the image browser as well as in the HTML text of the editor.
I uploaded a file with spaces in the name in 2.4.2. On selecting that, the 2.4.2 FCKEDitor Image Properties dialog appears as in the first part of issue1054.png with spaces in the filename as expected. The link information in the HTML extracted from the editor is also correct.
If I switch to 2.5, the Image Properties dialog appears as per the second part of issue1054.png. The spaces have been replaced with %20. This can possibly be considered correct in that strictly speaking this is a URL so should be URLencoded. However, the HTML anchor shows the URLencoding which isn't correct:
<p>Test<img width=\"588\" height=\"368\" src=\"../../../user/data/FEditorUpload/Image/bung%20en%20dore.JPG\" alt=\"\" /></p>
Is there a switch to turn this behaviour off?
