Hi Jeff Lane
The reason why you are seeing this issue is because the bug has been fixed in lucid but not karmic. We will attempt to back-port it to karmic-updates.
jknight: if that work-around works, then you are not using eclipse from Ubuntu (because it sets this variable for you already).
oliford: I am afraid I do not have any news for you on why this is happening - maybe the patch we got is only partial, maybe the svn plugin is broken. Have you tried the alternative svn implementation? The SVNKit or whatever it is called?
