Hi,
I am running OpenSuse 11.2, 64 bit, Gnome. I had Evolution mail client from repositories but I had problem with it so I installed newer version 2.28.20091119-1.1 (2.28.2 in About box) from special repository (Index of /repositories/GNOME:/Evolution:/snapshots/openSUSE_11.2).
I just want to check if this is the correct one (the newest) and I want to ask where should I report the bug (I found that the same one was fixed in Ubuntu and i don’t know if versions used are different). I also want to ask if you have the same problem. I filled few contacts in my contact list and when I write new message and I click “To:” button, I see all contacts twice there. Thanks for helping and sorry for newbie question 
I am running the same version of Evolution and am not having this issue. Yes, you have the most current version of Evolution. Do keep in mind it is a development release, hence the “snapshot”. If you check here Evolution: Download then you see that according to GNOME Evolution, this is, according to them, the most current version.
At this point, I am not sure if it’s a bug or not, since at this point we can not verify if it’s reproducible. By reproducible, I mean that others are experiencing the same thing you are. Even then, if that was the case, you’d want to file a bug report upstream.
