New tab button "+" in tab bar

Hi,

It seems there's an issue with the new tab button "+" symbol in the tab bar 
with recent versions when I click it I get the following error:

E16: Invalid range: 999tabnew

FYI I tracked down a similar issue on this CHANGELOG: 
http://ftp.uni-erlangen.de/mirrors/opensuse/factory/iso/Changes.20150316.txt 
regarding gvim where it says:

* The tabline menu was using ":999tabnew" which is now invalid.
