Have checked the problem image file against backups going back to 2008 (long
before I started using the KDE4 digikam).  The size, modtime and MD5 are
identical to the current version, so nothing has changed in the source file.

The uniqueHash is based on the complete image Exif data, plus the first 8Kb of
the file, plus the file size.  Assuming that the second and third of these have
not changed, is there any possibility that the format of the extracted Exif
data could have changed? - possibly only in some data-dependent way, which
explains why not all files are affected.

As you say, a difficult situation.  Currently I'm resigned to tagging all of
the affected images again, but I'd like to be sure that the work involved will
not all be wiped out by some possible problem in future.  Will raise a separate
bug for that.

Since nothing is reproducible, and current digikam creates and saves new tags
with no problem, the best option would be to close this bug as WORKSFORME?
