apport-bug refuses to report this bug, so here is the .crash file manually unpacked (minus the core file as it might contain details from my local passwd and shadow files).

[Andreas Schultz (aschultz)]

Removing the existing files in /var/cache/nscd solved the problem

Those files where left there from the jaunty version of nscd. It seems that the file layout changed and caused the problem.

A upgrade from jaunty to karmic should remove the old files.

[Andreas Schultz (aschultz)]

The attached nscd.preinst should take care of pruning the old cache on upgrades

please include...

This happened to me today on a Lucid VM which had not been upgraded from a prior release ever.
