Comment 9 for bug 177683

I tried using this patch and I found that in line backend.py:214 I was getting an error when I clicked on the rev number next to the files. (the /trac.fcgi/log/pages?rev=1 url) it was saying "int has no isdigit method". So I str() the rev on line 214 and it now reads "if str(rev).isdigit():" instead of "rev.isdigit()" and now it seems to work. thanks.
