Google Chrome - create gmail application shortcut

"Since I've started using Chrome I occasionally try to create a Gmail application shortcut - but without success yet. My Chrome version right now is 4.0.249.89 (beta) and OS Windows 7 (Home Premium) - but it didn't work with previous Chrome versions / Windows XP on a different computer either.
The Gmail icon is is not displayed in the shortcut creation dialog and no shortcut is created when clicking 'ok'."
