I noticed that kate thinks that a particular word is spelled correctly, even though is it misspelled. When I check the word using aspell or enchant utilities, they both correctly identify it as being misspelled. How can I tell which spell checker utility or dictionary kate/KDE is using and why it doesn't identify the misspelling?

Being one of the Kate Developers, I can explain the workflow like this:
When Kate or the system crashes, you loose all text buffers that were never saved. However, if you are working on a text file (that exists as file on disk), a swap file is created next to the file, called .filename.kate-swp. Now, if Kate starts again, Kate searches for these swap files. If found it replicates all edit actions that were recorded in this swap file, and your data is fully restored.
Rule of thumb: Always (and I repeat: alawys) work with files, not unsaved text buffers. That is good practice with everything you do on a Computer.
Kate is using now ~/.kde/share/config/katemoderc
From GUI: Kate menu → Settings → Configure Kate... → Editor Component → Open/Save → Modes & Filetypes
Select filetype:
Sources/Fortran, add;*.hto file extensions, raise priority from9to15(Should be ok, Max priority for.hwas inSources/C++which is9)
Close then reopen the files.

So I realise this is an old question, but I seem to keep revisiting this situation and maybe you are too.
KDE uses "Sonnet" these days as the spelling framework. Apparently it can use Hunspell underneath (and also Aspell, which is no longer maintained?)
Anyway, I needed to figure this out myself again today, and wanted to leave a note for posterity... the Sonnet setting in the KDE spell checking (Regional Settings, Spell Check) will cause a silent failure if your particular regional variant is not fully installed - in my case Australian English (en_AU).
Try starting KMail (for example) from a shell and notice:
So my distro did not automatically pull in my en_AU dictionaries, and setting that region for spelling did not complain about or change that situation.
This may be a source of your problem - also try disabling automatic language detection until you have your dictionary issues sorted.
