Bug #34373 fixed populating SHA1 sums for archive rows that store their text directly in the archive (not text) table. For the bug's “Version: 1.20-svn” a fix has been committed. However, bug #34373 also applies to 1.19, which has not yet had the fix committed.
I've tagged the revisions for backportting.
