[CDBI] overload problems

Hi,

I am using Class::DBI 3.0.14

I am very inconsistently getting the error :

Operation `.=': no method found,
	left argument has no overloaded magic,
	right argument in overloaded package
Class::DBI::Object::Has::Been::Deleted at
/usr/share/perl5/Class/DBI/Relationship/HasA.pm line 61.


Any ideas where to start looking for the problem? It's a modperl
environment and only happens 1 in 20 - 50 hits, generally after non use
for a while.

I can replicate it, but not any more the once so I can't break down the
code..
