[Evolution] Error storing Folder - Evo 2.4.1

[Gordon Burgess-Parker <gordon burgessparker gbpcomputing co uk>]

I subscribe to the Open Office Mailing list, which is a high-volume
list. (4000 posts a month). Sometimes I get the following error:

"Error while Storing folder 'Personal Folders/ITC/Software/Open Office'.

"Summary and folder mismatch, even after a sync

when exiting the folder. Is this because the folder gets over a certain
size limit, or is this a bug? I find I can cure it by creating another
folder and moving all the messages to it and then deleting the original
folder.

Any thoughts?
