Looking through the Debian changelog, it appears that
there was a similar problem between 2.4.23-1 and 2.4.23-4.
The switch to libdb4.8 was made in 2.4.23-1, but the
change to slapd.scripts-common made at that time (SVN
revision 1275) used "lt-nl 2.4.21" as the conversion
cutoff, so the export/import cycle was missed for systems
upgrading from 2.4.21-1.

This was corrected in 2.4.23-4 (SVN 1307) after being
reported in debbugs #593550. I see that the correction
does use "2.4.23-4" as the cutoff version number, so I
think that in Debian there would be errors attempting to
upgrade from a pre-2.4.23 database to one of the earlier
2.4.23 packages (but without doing any manual fixes) and
then up to the -4 version. But it also looks like 2.4.23-4
was the first of the 2.4.23 versions to make it into
Testing, so presumably there weren't too many people
affected by that gap.

In Ubuntu we have the situation that the "gap" includes
the version released in Maverick, so it seems likely to
affect more people....
