[Evolution] Latest libbonobo breaks Evo 1.5.9.1

["Patrick O'Callaghan" <poc usb ve>]

After updating my Fedora Core 2 system (using apt-get dist-upgrade) I 
now find that Evo has broken. The skeleton of the Evo interface appears 
but none of the components activate. I did a second upgrade on another 
machine, one RPM at a time, and the culprit seems to be libbonobo. When 
I run with CAMEL_DEBUG=1 I get this:

evolution-shell-WARNING **: Cannot activate component  
OAFIID:GNOME_Evolution_Mail_Component:1.5: Unknown CORBA exception id: 
'IDL:omg.org/CORBA/INV_OBJREF:1.0'

I'm using Evo 1.5.9.1, which is now a couple of months old, but since 
there are no official packages for FC2 I've been using the ones at 
http://people.redhat.com/dmalcolm/RPMS/, which haven't been updated in a 
while.

Is there anything obvious I can do other than recompiling 36 modules 
from CVS?

PS I'm sure I'm not the only one using FC2. What are the rest of you doing?
