If it crashes sometimes, it looks like the filters are not properly  
locked for concurrent access (my first feeling). And when I look at the  
accesses to LibBalsaMailbox::filters_loaded, and  
LibBalsaMailbox::filters, I see they are not protected.  
libbalsa_mailbox_filters_when() assumes that the filter list does not  
change in the meantime, either. Some either locking or reference  
counting would be in place there. How often does it happen? Is it at  
least sometimes reproducible?

This looks really fascinating...
