New version of nautilus-ubuntu appears to ignore ubuntu theme patches
I apologise if the title is inaccurate, the bug is a little difficult to describe in words so I'll just use screenshots primarily, although the issue is essentially nautilus looks like upstream nautilus, rather ubuntu patched nautilus. I first noticed this after opening a samba share on my local network (I have nautilus-share installed). However, I would not conclusively say that its related as I have not been able to reproduce it since then - nor do I fully remember the circumstances. I did not change any configuration files and even tried deleting the nautilus configuration files with no resolution.
The first screenshot is after I downgraded to nautilus-ubuntu-3.14 and libnautilus-extension-ubuntu-3.14 and is the view I had before the issue appeared, I've numbered areas where the change occurs.

- The close, minimize, maximize buttons appear in the top left of the window. Note that mousing over the global menu bar also shows the close, minimize maximize buttons as normal.
- Icon sizes appear much larger, this is present on the desktop too. Although strangely enough the 'home' icon is unaffected.
- The configuration button that ubuntu removes (atleast I assume they did) has reappeared.
- Although I forgot to take a screenshot showing it the global menu reverts back to that of the default gnome 'Files' master menu entry, rather File, Edit etc.
I solved the issue by reverting to nautilus-ubuntu-3.14 and libnautilus-extension-ubuntu-3.14. Without rebooting everything was back to normal with the exception of the File, Edit tabs appearing in the window rather than the global menu. However, that was solved with nothing more than a reboot.
I also had to downgrade BOTH nautilus and libnautilus to go back to normal - only downgrading nautilus did not fix the issue. I'm not familiar with how either package interacts (or its possible interaction with nautilus-share).
I just removed nautilus-share and upgraded, it appears the issue isn't directly caused by that package. At least its not caused by the package simply being installed.
I have the same problem I don't know how to downgrade.. I tried to use downgrade script but nautilus-ubuntu-3.14 and libnautilus-extension-ubuntu-3.14 are not in my repositories or cache .. please help
