What about this rather simple solution:

Package: perl-modules
Breaks: xfonts-traditional (<< 1.7~)

The action to achieve is: before the new perl-modules is unpacked 
(which would break xfonts-traditional.postinst due to missing (or 
better: relocated) File/Find.pm, ensure xfonts-traditional is either 
upgraded first or deconfigured - this should be sufficient for any old 
dpkg not to do trigger processing any more (as long as it is not in a 
configured state).

I tested this, and it seems to work:

No Pre-Depends or any other fancy stuff needed :-)
