[Bioperl-l] strange error after changing to RC1.5

Hi Allen,

When I add the line to all Bio::Annotation::*, we run into various other
errors, e.g. :
Can't call method "primary_key" on an undefined value at
/usr/lib/perl5/site_perl/5.6.1/Bio/DB/BioSQL/BasePersistenceAdaptor.pm
line 1325.!

What are these overloaded methods for?
Who/What is calling ->ne()?

I´ve tried using the latest cvs version with the Annotation classes from
december: This error is gone but then all SeqFeature tag_values are
stringified memory addresses:
/clone_lib="Bio::Annotation::SimpleValue=HASH(0x76883bb8)"

/tissue_type="Bio::Annotation::SimpleValue=HASH(0x76883ccc
~                     )"
~                     /clone="Bio::Annotation::SimpleValue=HASH(0x76883d14)"

/organism="Bio::Annotation::SimpleValue=HASH(0x76883d5c)"

/lab_host="Bio::Annotation::SimpleValue=HASH(0x76883dec)"

/db_xref="Bio::Annotation::SimpleValue=HASH(0x76883e34)"

/mol_type="Bio::Annotation::SimpleValue=HASH(0x76885360)"
~                     /note="Bio::Annotation::SimpleValue=HASH(0x76883da4)"

?
To make it even more complicated, I´ve dumped both seq objects (the one
all with classes from dec´04 and the bioperl-live with only the
Annotation classes from dec´04) there is no diff!?
The Seq, SeqI, RichSeq SeqFeature::Generic objects didn´t change since
then...
