[Aptitude-devel] Bug#1028046: aptitude: Segfault when updating package list while mirror update was running

Package: aptitude
Version: 0.8.13-5
Severity: normal
aptitude just crashed with a segfault for me when updating the package
list while a mirror update was close to be finished on the used Debian
mirror. (Haven't seen a segfault in aptitude for quite a while, so I
assume this is either a rather seldom race condition or — probably less
likely — triggered by a recent update of apt.)
