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.

These are the (exact) same symptoms I experienced in groovy a few days ago (see Q/A). Have you tried the "dist-upgrade" option?

Tried, dist-upgrade won't do anything on my machine (I suppose 12.04 LTS can't be dist-upgraded until another LTS come out).

dist-upgrade does not change what distribution you are on. It is simply a command which allows apt to install new dependencies, which is forbidden in a standard upgrade.

looks similar to this question: (rostopic and other commands fail after update)

No held upgrades here.

have you tried manual "sudo apt-get install ros-groovy-rosgraph" ?

As I said I have to stay on fuerte. I'm working with Pandaboards and getting groovy on them has been nigh impossible.
