Unmarked this merge request as a Work In Progress

Status changed to merged

mentioned in commit dfb0b5de

After this merged into master, master is complaining navbar_icon is undefined: https://gitlab.com/gitlab-org/gitlab-ce/commit/dfb0b5de3a33cc20f753f8594eb2a5278ede060e/builds

My guess is that master removed navbar_icon later after this MR created

It's renamed to custom_icon in c57471dd

@godfat I'll have a look now thanks

@iamphill No problems. Let's see if https://gitlab.com/gitlab-org/gitlab-ce/commit/f435eb6f35ab755dae1fd45d9aa577f6896eae7b would fix it :)

@godfat Just saw you fixed it thanks!
