When I install today's 1.5.2 version and install no plugins except the filter plugin, I can click on any folder but will always see the messages of my inbox. The folder name on the top left is correct though.
Empty folders are displayed correctly also.

I'd like to add that I see this behavior as well in the latest squirrelmail-20070411_0000-SVN.devel snapshot. As it breaks Squirrelmail and not just the filters perhaps the priority should be raised a bit?
