Control: reassign -1 src:glib-2.0
Control: retitle -1 For locale th_TH, %x gets rendered in en_US fashion
Control: severity -1 important
Hi Nachanon, dear glib-2.0 maintainers,
@Nachanon: thanks for your testing...
@glib-2.0 maintainers: We encountered a bug in mate-screensaver that
finally might boil down to the way how the GDateTime handles th_TH
date strings in glib-2.0. Please see below for further explanations
and possibly review the bug history. THANKS!
@glib-2.0 maintainers: I'm not sure about the severity this bug should
be set to. I guess, i18n and localization fixes have a high prio by
the release team, thus settings this to "important". Feel free to
downgrade if you are of a different opinion.

This really smells like this needs to be further processed by the
maintainers of Debian package glib2.0.
Can you please test with LC_TIME=th_TH and
LANG=th_TH.<your-common-encoding>, as well, and report back to the bug?
Anyway, reassinging this bug to the glib-2.0 src:package...
