roscore crashing after automatic update

edit

I just sudo apt-get updated my fuerte installation and roscore now crashes.

Here is the message

auto-starting new master

Log files are all empty.

I tried removing and reinstalling ros but it didn't work.

Seen this other question but it's the other way around for me and besides being on 12.04 LTS, I can't even do a dist-upgrade.

Also tried this (recreating the workspace) but it didn't do anything.
