Please note, the validator for well formed html is now gumbo. Its validation is strict to the html standard, so things link using numeric enties to encode linefeeds, and other strange things, like incomplete doctypes and things like that may be causing an issue. The only real way to get this fixed is a testcase just as DiapDealer requested so we can see what is causing the issue.

ps: I wonder if this is just the case of the pluginrunner trying to validate a new css file as xhtml when it should leave it alone. I will take a peek at the code to see.
edit: Nope, after looking at it, the code in PluginRunner looks correct.

Thanks,

Kevin
