SVN commit 579876 by amantia:

Save As asked for confirmation of "save before close" for modified files due to the setEncoding() call. This was confusing and could result in data loss as well. For now, remove the possibility to change the encoding in the save dialog (users should change the encoding and save later or save and change later).

Possiby fixes #131728  (I cannot reproduce it with this version).

I never change encoding when saving as, but still this bug occurs. 

Yes, but this is a bug in Katepart which I workarounded for 3.5.5.
