[Bug 645647] Re: update-apt-xapian-index crashed with SIGSEGV in pkgCacheGenerator::pkgCacheGenerator()

[Robert Roth]

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug. I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.
