I'll try that now and report, but that seems a bit improbable to me as
this is my locale setup:

$ locale
LANG=en_GB.UTF-8
LANGUAGE=en_US
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC=tr_TR.UTF-8
LC_TIME=tr_TR.UTF-8
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY=tr_TR.UTF-8
LC_MESSAGES=en_GB.UTF-8
LC_PAPER=tr_TR.UTF-8
LC_NAME=tr_TR.UTF-8
LC_ADDRESS=tr_TR.UTF-8
LC_TELEPHONE=tr_TR.UTF-8
LC_MEASUREMENT=tr_TR.UTF-8
LC_IDENTIFICATION=tr_TR.UTF-8
LC_ALL=

If this and the other recommendations from your other message don't fix
the problem, I'll report a bug.
