OK, thanks. If something like this happens again, I'll do it that way.

For the current situation, the next upload of pilot-qof does depend on
libqof-backend-qsf0 and libqof1 and is due in a day or so. The next
upload of libqof1 no longer depends on the backends itself - breaking
the circle and closing the bug. Is that sufficient or does the next
release of libqof1 still need to conflict with pilot-qof <= 0.1.1-1 ?

(0.1.1-1 is in experimental and does not know anything about the qsf
backend.)

The next upload of pilot-qof is 0.1.1-2 (simple change from experimental
back to unstable in debian/changelog and the addition of
libqof-backend-qsf0 to Depends: in debian/control.)

The next upload of libqof1 is likely to be 0.8.0-1 but this won't be
ready until after pilot-qof 0.1.1-2 reaches testing. Does there still
need to be an interim upload of libqof1 with the conflict?
