I have the same issue, and have started creating a patch for  
Search::Xapian in bug #230[1].

This bug is meant to be for the maintainer to use before releasing the  
packages, as it generates the code from xapian-core exceptions, rather  
than hardcode each exception in the bindings. I run a patched version  
of 1.0.4 in production and catch Search::Xapian::DatabaseModifiedError  
succesfully there with the exception-classes and patched Enquire.xs.
