[Bug 1220013] Re: python-apt can SIGSEGV when encountering Packages stanzas with no Description field (was: update-apt-xapian-index crashed with SIGSEGV in File())

[Thomas Ward]

Hello.

It is still unclear whether this is still an issue in apt-xapian-index
or the underlying python apt bindings.  I am marking this as Incomplete
for apt-xapian-index as this is still marked as affecting it and has
been since 2015, and the Trusty that was affected is End of Life.
Please verify if this remains an issue or not.

** Changed in: apt-xapian-index (Ubuntu)
       Status: Confirmed => Incomplete
