With older version of this script I sometimes got -bash: [: 1: unary operator expected after various git commands:

++ history -a
++ set_prompt
++ git --no-pager branch --no-color
+++ _git_branch
+++ local i c=1 only_local_ref=n has_r=n
+++ '[' 1 -lt ']'
-bash: [: 1: unary operator expected

Perhaps there's namespace clash with bash completion project:

/usr/share/bash-completion/completions/git:_git_branch ()
/usr/share/bash-completion/completions/gitk:_git_branch ()
