Please describe the problem:
The location bar disappears permanently when displaying folders with a long enough name.
To fix it, all the user can do is open the parent folder in a new nautilus window.

Steps to reproduce:
1. from nautilus, create a directory with a name about ~90 characters long, 
2. enter that directory, verify everything's ok, return to parent folder
3. add another ~10 characters to the directory name
4. enter that directory again.


Actual results:
the location bar disappears from view

Expected results:
nautilus shows the contents of the directory, and everything else should be ok

Does this happen every time?
this happens with any directory, as along as it has a long enough name. I still haven't found any way bring back the location bar, all I could do is open a new nautilus window.

Other information:
this bug may depend on factors like theme used, if the window is maximized, etc.
