I've been looking into this a bit more, and I think that you don't need a try/except - it's enough just to add "ignore_error=True" to the call to read_lines. It also looks like this is a general problem of importing a label where the revision doesn't exist in git. For example, if you create a p4 label, then clone at the revision after that, you will get the problem. I've got a test case and a modified git-p4.py, but I haven't yet got to the point where I'm convinced it works. I think the fix is pretty much what you've shown (replacing try-except with ignore_error) but I'd like my test case to be a bit more convincing. Thanks!
