There is a similar issue with apt-get that occurs during an
installation of Debian on the NSLU2 which is an arm based device.
During the installation process, apt fails, and the following log
messages are written to /var/log/syslog:
Dec 2 00:18:18 base-installer: info: Available initramfs
generator(s): 'initramfs-tools'
Dec 2 00:18:19 apt-install: Reading package lists...
Dec 2 00:18:19 apt-install:

Dec 2 00:18:24 apt-install:
Dec 2 00:18:24 apt-install: You might want to run `apt-get -f
install' to correct these:

is not installable or
Dec 2 00:18:24 apt-install: inet-superserver
Dec 2 00:18:24 base-installer: error: exiting on error
base-installer/kernel/failed-package-install
At this point, the problem looks like an issue with the repository,
but running 'apt-get -f install' manually shows that apt-get segfaults
while building the dependency tree.

Martin Michlmayr has found that after manually installing a deb,
apt-get works again [1].
Below is a backtrace of apt-get before the segfault. I rebuilt apt
with debugging information.

I am only too happy to help debug this problem, so please let me know
what else you need in terms of output, etc.
