[sylpheed:33002] Moving a message to an IMAP folder fails

[Per Danielsson]

Hi,

When I try to move a message from a local folder to an IMAP folder I
get the following error message in the log:

    ** LibSylph-WARNING: [11:55:09] can't append message to oz-users
    
    ** can't append message to oz-users
    ** LibSylph-WARNING: can't append message C:\Users\pd\AppData\Roaming\Sylpheed\Mailboxes\Mail\oz-users\3912

I can't see anything strange in the message when looking at it with
View -> Message Source.
Is there any way I can get a more verbose log?

(I'm using Sylpheed version 2.5.0 (GTK+ 2.10.14 / GLib 2.12.13) on
Windows Vista.)

Cheers,
