--- Comment #4 from Yorik van Havre yorik.vanhavre@gmail.com 2010-12-05 09:46:41 CST --- I just notice now that debian recently modified the ia32-libs package and some libraries are not in /usr/lib32 anymore, but in /lib32, so they are not found by wine at configure, some of them very likely to be related with the systray icon (png, dbus). I'll try to solve that and see if there is any change.
Lots of people use steam and nobody reported that issue so I suspect it is a pretty local problem...
