>Description:
pkg_delete segfaults when deinstalling packages with a certain kind of
corruption in the +CONTENTS file. I am not sure where this problem originated,
(probably either portmaster or portupgrade),
but for sure pkg_delete should not segfault on any kind of corruption.

The segfault happens with and without -f option.

This happens in 7_STABLE as of 2009-06-01 as well as 7.2-RELEASE.

>How-To-Repeat:
(replace foobar by a package to be deleted)

echo '@pkgdep' >>/var/db/pkg/foobar/+CONTENTS
pkg_delete -f foobar

>Fix:
