Don't wrap text on ActionBar Android 4.x navigation tabs

I use ActionBar.Tabs (4.x), and if I have a slightly longer text in the title, it is wrapped in 2 lines, just in the middle of the word.

Like: text = ABCDEF in the tab:

Abcde

R

This is very ugly. See screenshot

How can I prevent ActionBar.Tabs from wrapping text and making tabs wider? Thanks
