mail-notification does not support evolution 2.6. This is easily fixable with an ebuild update.
Created attachment 83013 [details] mail-notification-2.0.ebuild The new ebuild basically detects which version of evo you have installed, and uses that to apply the correct patch (separate attachment on this bug)
Created attachment 83014 [details] files/mail-notification-2.0-evolution-2.6.diff This is a patch that is the same as the 2.4 patch, but w/ 2.4 replaced by 2.6.
Thanks a lot. In CVS.
