It turned out that this was not a driver problem, but a bug in the
libdbi library itself. I've checked in a fix today. I assume you won't
be able to wait until the next libdbi release, which may take some
time to be picked up by package maintainers. If you feel comfortable
with installing libdbi from the sources, please use the appended patch
for src/dbi_main.c.

Markus
