I just enter this bug http://bugzilla.ximian.com/show_bug.cgi?id=75379
for the template column problem
I can't seem to reproduce any of the other problems on the latest svn code.
I think the image and style problems could be specific to t he version of apache. I can't reproduce it on apache 2, are you using apache 1.x?
I can't produce the weird problem with the 0 either. I wonder if it has to do with culture settings and maybe doesn't happen for me because my culture settings are different.
