git-browser and branch names

Hi,

I've been using git-browser hooked up to gitweb for several weeks now (git 1.5.2.1), and it's going great. However, I've hit my first bug: it seems that certain branch head names cause the whole diagram (and log lines, etc.) to fail to render, only displaying the "Starting from: all <repo>.git heads" stuff down the bottom. As to the various names I've tested:

okay: master, 2.5j, 2.5-dev, a.b, 2-5, 2.b, b.2, 2.5.0 fails: 2.5, 2.6

I've experimented by just using 'git branch -m <old> <new>' to rename a branch that I'd prefer to just call '2.5', so I'm pretty sure that I'm not causing things to break myself.

It seems that it's when the branch name looks like a decimal number, but there's nothing that appears in Apache's error_log. This leads me to believe it's a Javascript bug.

Can anyone give me pointers or suggestions as to where to start debugging this? Anyone else encountered this?

Thanks,

Dave.
