Best crashes when rendering results from mail backend

[Jens Auer <jens auer-gmane betaversion net>]

Hi,
I just installed beage 0.1.3 on my Ubuntu Linux system by using the 
packages provided from the dapper repository. Indexing and searching 
works fine, except for the mail backend which end with a SIGSEV. I 
located the problem to the mail backend by using --allow-backend mail. 
The output of Best form the command line is:
Reading settings from Config
If you're wondering whether Best is working check your notification area 
(system tray)
SetSource:

Done Rendering: .94s

(best:12920): GLib-GObject-WARNING **: cannot register existing type 
`ESourceList'

`G_TYPE_IS_OBJECT (object_type)' failed

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

I'm not sure if this is a problem from Best/Beagle or the Ubuntu 
packages, so if anybody has a hint, I would be glad.
