depmod crashed with SIGSEGV in strcmp()

[Matt Jackson]

Binary package hint: libc6

I'm finding that I'm continually getting SEGVs from various apps (depmod, Firefox, google desktop indexer). Logs show

Expected: depmod to update module list
Instead: received a SEGV

Results in not being able to update kernel version.

Hmm. It was always failing trying to do a apt-get dist-upgrade and not being able to install linux-image-2.6.28-15-generic_2.6.28-15.52_amd64.deb. Note that sudo depmod -a would produce the core dump even without apt-get.

I decided to try and install the package with dpkg -i and it all worked fine. A straight sudo depmod -a now works too.
