Unity 3.4 and svn ignores

I have read the following articles and answers but I just can’t get svn to play nicely with Unity any more (had no problems in 2.6).

http://unity3d.com/support/documentation/Manual/ExternalVersionControlSystemSupport.html

It seems if I ignore the Library items suggested in those articles, the project will break (missing scripts on objects etc). If I don’t ignore them, making the smallest change to my project requires masses of Library stuff to be checked in each time. And yes, I do have external version control enabled. Is that last article on the Unity website up to date?

Any pointers would be greatly appreciated.

Thanks in advance

Here are the only files from the library folder we have under version control (all of these have extension .asset):

EditorBuildSettings
TimerManager
DynamicsManager
BuildPlayer
AudioManager
BuildSettings
EditorSettings
InputManager
MonoManager
NetworkManager
QualitySettings
TagManager
ProjectSettings

This, and of course all assets and their meta files.

Generally, this works fine. We had the odd terrain texture disappear in a previous project (around Unity 3.2 ish… don’t know if it was a Unity issue).
