Not sure exactly if this is your problem, but recently someone with a similar 
update history hit a similar problem, which could be solved this way:

Please check if you have some file
    ~/.local/share/mime/packages/user-extension-html.xml
around. If so, remove it, this is a file for some old hack to register the 
default browser, using a custom MIME type. And which seems now to be preferred 
over other MIME type definitions of files with the extension ".html". But 
sadly lacks the information that HTML files are a subtype of plain text files, 
thus KDevelop does not try to load a text editor, but instead tries to load 
whatever KPart is chosen as preferred MIME type handler for 

Once you have removed that file, run
    update-mime-database ~/.local/share/mime
so the actual MIME database (generated from those files in mime/packages) used 
(indirectly) by KDevelop is up-to-date and has the normal definition of HTML 
files again, which also defines them as subclass of plain text.

You might need to restart KDevelop first though, perhaps some data is also 
cached in the runtime instance.

Did this solve your issue?
