[Evolution] [evo1.4.0] "Spell Checker Document" doesn't work but not set greyed.

Hi, there,
In evolution 1.4.0, if I uncheck the option of using spell checker in
[Settings] dialog, the "Shift+Ctrl+L" ("Spell Checker Document" in
"Edit" menu) won't work.

Is it a bug or a spec feature. Hopefully, it should be greyed in this
case.

Thanks.
Calvin
