[Evolution] IMAP subfolders not accessible after upgrade to 1.2; Settings crash evolution

[Wernig Markus <public wernig net>]

Hello
I am using evolution on SuSE 8.0 with ximian-gnome as default desktop.
Today I kind of upgraded my ximian: not through red carpet, but usin the
installer downloaded from go-gnome.org. Everything seemed to work fine.

Problem: since the "upgrade" (1.08 -> 1.2) evolution cannot access any
subfolders on my cyrus imap(ssl) server. The mails in the top level
directories are displayed correctly. As soon as I try to access a
subfolder in the same top level directory, I get an error of the kind 
[... Mailbox /subfoldername does not exist] (AFAIR, sorry. I'm not at
the desktop at the moment)
It seems like evolution were not prepending some information needed.
The cyrus is configured with "altnamespace: yes", i.e. all top level
directories are on the same level as INBOX and not subfolders thereof.

Also, I cannot access the settings anymore; as soon as I go to
Tools->Settings, I am told something like "the component for type mail
has exited. You will need to restart evolution ..." So no chance to
change any folder settings.

Do you have any idea what to do?

ps: ran killev an oafslay afterwards, rebuilt the config from scratch.
