Cursor movement issue when global-linum-mode is enabled

[Vineet Naik]

Hello,

I am using the latest version of Damien Cassou's emacs-snapshot[1] on Ubuntu 12.04

After it was updated yesterday, I noticed a weird behaviour of C-p skipping a line when 

moving up, ie C-p moves the cursor 2 lines up instead of 1

After disabling some of my initializations, I figured out that this happens only if 

global-linum-mode is enabled. 

Has anyone else faced this issue? 

my emacs version: 

"GNU Emacs 24.3.50.1 (i686-pc-linux-gnu, GTK+ Version 3.4.2)

 of 2012-12-03 on chindi02, modified by Debian"
