I’m also having this issue. It’s caused by the presence of the file
/usr/share/hunspell/de_DE_frami.dic (and similarly named ones) on my system.
Here’s what happens: in lingucomponent/source/lingutil/lingutil.cxx,
GetOldStyleDics("DICT") attempts to load dictionaries from /usr/share/hunspell.
It tries to sort them by language, using the LanguageTag class and its
liblangtag backend. It also tries to be smart and turn the first '_' character
of the dictionary filename into '-' if no '-' was present, in the hope of
obtaining a locale string from which LanguageTag can derive a language
identifier. In my case, however, this yields "de-DE_frami", which is not a
valid locale. LanguageTag passes it to liblangtag, which tries to construct an
error message ("Invalid character for tag: '%c'", '_') but segfaults in the
process.
I have not attempted to find out why liblangtag’s error handling fails, but at
the core of the issue is the GetOldStyleDics code. Easy fix: after replacing
the first '_' by '-' (if no '-' was present), if another '_' remains, delete it
and any trailing text.
I don’t have the hardware to compile and test a patch, unfortunately.
By way of verification, I tried ‘mv /usr/share/hunspell
/usr/share/hunspell-bck’ and LO started normally. When I moved the directory
back, the crash occured again.
