Ahhh, you are right.

While amd64 is most probably the main target architecture it would be a
shame to loose i386 and there might be some hidden problem which in the
end also affects amd64.

So I did not yet considered this last resort and hope for some help from
people who are more confident with gdb debugging than I am (Ive read
here frequently some phrases like "10 minutes of gdb debugging" but I'm
afraid it would take me 10 hours - I'd happily join a "Gdb for Debian
maintainers" workshop at Debconf, thought.

Well, adding xvfb was the usual trick to cope with "unable to open X11
display" messages and thus I added it ...

Kind regards
