The problem with math symbol display does affect ru_RU.KOI8-R and=20
ru_RU.UTF-8 locales (and in both cases, may be workarounded by setting=20
LC_TIME=3DC).
I can't speak for other locales. Some more analysis of Qt source may give=20
the answer, but unfortunately I don't have time for that.

A possible solution for debian package is to provide lyx-qt-workaround=20
script that imple,emts workaround (LC_TIME=3DC exec /usr/bin/lyx-qt "$@"),=
=20
as one more alternative providing /usr/bin/lyx. Which one (lyx-qt or=20
lyx-qt-workaround) will be set by default, may be asked in a=20
medium-priority debconf question (defaulting to workaround enabled, unless=
=20
some unwanted side-effect is found).
