Using WINE apps under the menu is OK with that weird spring “Launcher” icon but it’s good to have old icons you are familiar with.
I found a post on the excellent Ubuntu forums dealing with problem:

Coincidently, the output of wrestool -x –output=. -t14 ~/.wine/drive_c/Program\ Files/MSN\ Messenger/msnmsgr.exe …leaves you with a .ico file which you will then have to convert to a SVG (vector based format) to use in Ubuntu’s menu
I went a slightly different route by using http://wineicons.sourceforge.net/ to extract the icon from the exe as a PNG Bear in mind that the “Change Icon” dialog will not show the icons in the directory that you navigate to. Click OK and then the dialog will ask you to select from the compatible files it find in the directory (confused me for about an hour!)
