This bug has been filled in response to #636694. While the problem has
been fixed by stopping TMPDIR usage in the locales-all postinst, there
is still a need for some space available in /tmp for upgrading or
installing packages with debconf templates. On one side the problem is
more likely to happen because tmpfs on /tmp is now the default in
trixie. On the other hand systems have more RAM, so bigger /tmp, so the
problem is less likely to happen.

Yes, let's close it for now, we can always reopen it if it poses a
real issue when more users upgrade to trixie.
