Element i in namespace '' encountered in para, but no template matches.
I see this printed on the console when building evolution-data-server with gtk-doc:
Element i in namespace '' encountered in para, but no template matches.
but I've no clue how to figure out where exactly the problem is, thus I cannot fix it. Is there any way to find that out, please?
The print is nothing new, it's there for several releases, I only always forget to ask. I'm currently using gtk-doc-1.29-3.fc30.x86_64.
