Package: libsearch-xapian-perl
Version: 1.2.3.0-1
Severity: normal
I have a reproducible segfault in xapian, that seems to occur when the
database is being first created, but oddly seems depenadnt on a
particular input corpus being indexed -- similar sites with other content
don't crash.

Tried upgrading to unstable's version of the package, still seeing
the segfault.
