The most effective thing you could is to investigate the cause of these 
errors.
prsumable they are due to the the new class you added.
Also,  polymorphic archives a measurable slower than the non-polymorphic
versions.  So if performance is important to you, then consider changing.
I realize that this will result in more instanciated code, but the execution
will be faster.

Finally, you might consider moving to the most recent version of the
library.  It's much harder to help someone who's using an older package.
