In fact, using Products.ContentWellPortlets from github solved my problem. I was able to update Plone to version 5.2.4 and sites created in this version do not have the problems when compiling Diazo themes.

Can you check if these things work in 5.2.4 (does not in my 5.2.somethingelse)

1. Copy barceloneta TTW and edit files in themes subfolders
2. Using a unicode character in some of the less (css) and compile or save ( for example .someclass { content: "©" } )
