This is the same as #304604: locales uses debconf, debconf uses perl,
and perl has heap corruption in its exit() path (more specifically, the
PerlIO code seems to call fclose() twice on the same file handle).

The new glibc has more draconian heap checking and calls abort() when it
detects corruption, which causes the post-inst script to die (due to
"set -e").

Now that glibc 2.3.5 is in unstable this will start to hurt.
