-This code introduces various issues with BibLaTeX. I've tried
-to remove it, which fixed BibLaTeX issues, but broke Nameref.
-So I reintroduce it, and will try to resolve BibLaTeX issues
-in a different way.
+We need to load Nameref here, otherwise lot of documents
+that use Hyperref fails. This caused issues with BibLaTeX,
+as both Nameref, BibLaTeX and TeX4ht redefine ifthenelse command.
 
+So we load explicitly the Ifthen package, let Nameref redefine it,
+and then revert to it's original definition before applying of
+TeX4ht hooks.
