Bug#674951: [libapt-pkg4.12] aptitude crashes while updating packages list

[marc poulhies <dkm@kataplop.net>]

Package: libapt-pkg4.12
Version: 0.9.7.4
Followup-For: Bug #674951

I'm having segfault when using aptitude/apt-get/dselect:
$ sudo apt-get update
...
[ 1741.499021] apt-get[4759]: segfault at 7fad99d27144 ip 00007fad9b35f5f0 sp 00007fffbc44f2e0 error 6 in libapt-pkg.so.4.12.0[7fad9b2bf000+126000]

But doing:
sudo apt-get update -o APT::Cache-Start=100000000

works.
