In the following sentence... The Catechism of the Catholic Church defines virtue as “an habitual and firm disposition to do the good… he pursues the good and chooses it in concrete actions (CCC 1804).” ...Libreoffice Grammar Check (English USA) returned "bad article" for "an habitual" and suggested "a habitual." However, English usage allows "an" before a word beginning with "h", even though the "h" be hard, as in "an historical occasion".
REPRODUCIBLE with LibreOffice 3.5.4.1 (Build-ID: 7306755-f4f605c-738527d-1cf4bc1-9930dc8) on MacOS X 10.6.8. Therefore changed Status to NEW and Platform to All (not Linux only). NB: I can reproduce the problem only with "... an habitual ...", not with "... an historian ...": the 2nd example mentioned is not marked as wrong. So "historian" seems to be included within some exceptions list, but "habitual" not. This is a Grammer checker issue, therefore changed the Component field accordingly to "Linguistic".
Thanks for the bug report. It will be fixed soon.
