Package: libm17n-0
Version: 1.6.1-1
vlc 1.1.3-1 segfaults when it tries to display message saying that
file supplied in command line does not exist. This happens when plugin
from uim-qt 1:1.5.7-9+b1 tries to initialize m17nlib.
mlocale_set() call returns NULL, while code in mlocale_init() doesn't
expect it despite mlocale_set()'s documentation saying NULL can be
returned.
And mlocale_set() returns NULL because setlocale (LC_CTYPE, name) call
in make_locale() returns NULL, probably because vlc is multithreaded.
(Changing locale in one thread of a multithreaded application does not
sound good.)
