Broken gitk in Ubuntu

At work, we use Ubuntu both on our servers and workstations. Today, I was startled by the command gitk not showing git history, but instead an error:

Error executing git log: wrong # args:
   sholuld be
"safe_open_command_redirect cmd redir"

Fortunately, I've already seen the source code of gitk (and learned some tcl to understand and modify it), so I copied it to ~/bin and quickly found a fix.

I checked the gitk at GitHub and it seems Ubuntu released a version in the middle of a refactoring that wraps calls to open.
