Rectangle text in Ubuntu

Recently I have downloaded the latest source code of Open Office 3.10. Few days ago, there was an update from Ubuntu Update manager. As usual I'll briefly browser through what is going to be install in my Linux. But this time I did not browse through it, and I just install. Then in my next login, all the text or whatever text can be read in English are change into rectangle. I was in the situation where there is no English text at all.

In order to solve this problem, I have to un-install the pango v1.24 through runlevel 2 because that is the only place I can see English text. Restart after un-install process has been done to take immediate effect.

I guess there must be some dependency library having some conflict with pango library during the update. Need to find out more on this.
