 Occasionally when running some python code that uses Xapian databases I
 encounter a coredump in the Xapian python bindings. Please advise on what
 debug information would be useful, or how I might avoid this issue
 programmaticly.

 Running the following packages on RHEL 6:
 xapian-bindings.x86_64 0:1.2.15-1
 xapian-bindings-python.x86_64 0:1.2.15-1
 xapian-core.x86_64 0:1.2.15-1
 xapian-core-libs.x86_64 0:1.2.15-1
