Changing user password upsets evolution, solution needed.

I am running Fed35 workstation (thus Gnome) using evolution for mail I want to change the password for user (myself). But I remember from a couple of years ago that this gave problems with evolution and gnome-keyring: something like being prompted on startup evolution for a password to unlock the login keyring and that nothing I tried (after internet search) worked. I "solved" the problem then by installing thunderbird which did not have this problem and erasing evolution. My question now is: how can I change the user password and evade the problems caused by evolution, gnome-keyring, pam whatever. That is how can I change everything needed in one go. I do not even understand what is happening because I have never needed to study the arcane mysteries of gnome-keyring/pam etc. (and when I looked the docs I found were not very clear). Can somebody refer me to a detailed schedule of what is actually happening so I can understand it and work out the steps needed myself. Or better yet give me the necessary instructions. (I am getting too old for these kinds of things :)) AV
