When I label a project, I can use the colon character in the name, like this: "Release: Version 1.0".
However, if I want to rename a label, the colon character is no longer an allowed character, hitting the colon key produces nothing. Colons present in the label is allowed to stay but if I delete them I'm not allowed to put them back.
Version 2.0.4.
