Having a separate -dbg package for simpleopal does seem like overkill, and I
think the ftpmasters would (be correct to) reject it. Either of the other
solutions seems viable.

Removing debug symbols for simpleopal only impacts the ability to
get good stack traces from simpleopal's own code, not from libopal; simpleopal
has few users in popcon, and I suspect that if it ever crashes, it's much more
likely to be caused by a bug in the library than in simpleopal itself.

Having the -dbg packages conflict doesn't seem like a practical problem,
because if an Opal-based application (like Ekiga) is crashing, you only
need the debug symbols for the version of Opal that it links against,
and don't care about the other version; so you'd never need both versions
installed at the same time. If you do this you should remember to keep the
appropriate Conflicts: entry to ensure a graceful upgrade from lenny to
squeeze, though, even after intermediate versions have disappeared from the
archive.

(Disclaimer: I don't use Opal or know much about it; I'm only looking at its
bug list because I was reporting an uninstallability bug, and you seemed to
be asking for advice here...)
