An example of the corruption

Description of problem:
In RTL locales (Persian and Arabic locales tested), nautilus menus containing translated texts doesn't appear correctly and they are sometimes hardly readable. While the menu text is expected to be right aligned and shortcut keys come in left (mirroring the way they appear in LTR locales), some of the menu texts appear floating in between and some of them are in left, overlapping with shortcut key descriptions. 
This is only observed in nautilus and other gnome applications (e.g. gedit and gnome-terminal) work just fine.

Version-Release number of selected component (if applicable):
nautilus-2.91.90.1-1.fc15.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Make sure that there is no instance of nautilus running 
2. Run: export LANG=fa_IR.utf8
3. Run nautilus
4. Open some menus
  
Actual results:
Menu texts doesn't appear correctly. An example is attached.

Expected results:
They should appear correctly!
