But it doesn't hurt to build the old API and AFAIK there is no
noticeable (dis)advantage. The only change is more code, ok and a
little nicer code for the existing non-Glade tooltips.
If you really want, do it. It's probably not that worse as I told but
still not strictly necessary.

As I told, the tagmanager patch is cool.

About the g_strcasecmp() problem:
I don't think the right solution is to copy the old, broken code from
GLib into Geany. As the docs mention, there is a reason why this
function is deprecated and should not used.
IMO we should rewrite the code which uses this function with the
alternative functions mentioned in the docs.

gtk_widget_ref() vs g_object_ref() is ok, obviously. These are from
copy&paste code from Glade :).
