Not a bug, feature, it's supposed to maximize windows that are "almost" maximized. It does that on window map, so switching workspaces, as well as launching the app, should maximize:
$ gconftool-2 --get /apps/metacity/general/auto_maximize_windows
You can disable with: $ gconftool-2 --set --type bool /apps/metacity/general/auto_maximize_windows false
Please reopen if that does not "fix" your issues.
