Bug#661502: apt: "apt-cache search" segfaults if "apt-get update" encountered "a section with no Package: header"
Package: apt
Version: 0.8.10.3+squeeze1
Severity: normal
"apt-get update" currently results in the following error messages on
Squeeze and Sid:
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/security.debian.org_debian-security_dists_squeeze_updates_main_binary-amd64_Packages
E: The package lists or status file could not be parsed or opened.
If I then search for something with e.g. "apt-cache search .", it
reproducibly segfaults on Squeeze.
On Sid, it just errors out with the same error message as "apt-get
update".
Feel free to close this bug as fixed in Sid if you don't think it's
necessary to fix this in Squeeze.
