There is no glibmm documentation package. It is expected that should be glibmm24-docs, as it is for gtkmm24 (glibmm24-docs).
The glibmm docs are in the devel package.
I'll eventually split them out. I need to fix the devhelp paths for f-10 anyways.
Actually the issue is that the documentation is not invisible in DevHelp. Is it possible to fix the issue for f-9 too?
I supposed you meant 'not visible' :-)
Yes, I just fixed this for F-10, I'll push F-9 updates eventually.
