Subject: [PATCH] tdf#116586 fix LibreOffice crash by Hungarian personal
dictionary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
"AkH. 11. (old orthography)", caused by bad handling of forbidden words
of alias compressed dictionaries during run-time dictionary extension.
Note: accepting also all – previously forbidden – affixed
forms of the modified stem is a removed function: "Grammar by" spell
checking (for example, in LibreOffice via SPELLML interface of Hunspell)
supports user words with affixation and compounding.
The original idea was to add substandard or interfering words
as forbidden words – but with flags – to the dictionary, and adding
the stem to the personal dictionary could “switch on” the affixed
forms of the word, too. Now the suggested method is using
"Grammar by" personal dictionaries, as in LibreOffice:
