You were right about this. I filed the following ticket


Here's how to install the bug fix: The last entry in this ticket links 
to the changeset


which contains the bits of code I changed in order to make it work. The 
changeset contains the patch. Every closed ticket should have a link to 
a changeset (If the closed ticket does not contain a link to a 
changeset, ask the person who closed the ticket).

If you encounter a patch in a changeset

1) Don't panic
2) Click on the link in order to get to the changeset
3) Check "Files" (these files have been changed). Follow the link, in 
this case


Notice the revision number, 3207. This is the exact version of the file 
containing the bug fix. Don't download the most recent version, download 
this exact version just to make sure.

4) Scroll down, and you will see a link "Original format". This is the 
link to the changed file. Download it and replace your old version with 
this new one (consider backing up your old file)

(Another way of applying the patch would be to click "Unified diff" on 
the changeset page...but I guess you would have to manually rename the 
paths in the diff...so this might be an advanced solution, but 
inevitable for patches where a lot of files have changed)

If the bug fix doesn't work, please feel free to re-open the ticket. You 
need an account to do this. See


for details.

Any questions? Please feel free to ask. I'm happy to explain Trac in detail.

>> 3.2 The "old" MapBender behavior ist restored (my priority TWO)
>> ----------------------------------------------
>> If a "hidden" wms could be used (again) for generating overviews, a
