I discovered firefox --debug and tried it with ddd, but it
didn't really tell me anything useful.  After trying in
desperation against a number of gecko-sdks I finally worked
out that I needed to build my component using
'pkg-config firefox-xpcom --libs --cflags'[1] rather than
the gecko-sdk.  Why the SDK no longer works going
from FC5 to FC6 (and had a go at -Wl,--hash-style=sysv with
the latest Mozilla 1.8 gecko-sdk too, just in case) I don't
know.

So, a new question, why should this be the case?  (It'd be
useful to know should I ever manage to put together a component
I want to distribute.)

typo stopped it working.
