[Bug 44828] Evolution looses some mails on the way from the inbox to the screen

[Blue]

Public bug reported:

Binary package hint: evolution

After upgrading from breezy to dapper, and after a week or to with dapper evolution started to forget about some mails that ARE received. For example, in some folders the mail arrives from the pop3 server (the mail can be checked for example in 
/.evolution/mail/local/Inbox.sbd/subfloder.sbd/FOLDER but however are not displayed on the screen.
It is not an isolated problem, now only a few percent of the new  emails are actually displayed. 
Deleting summary/index files (forcing evolution to recreate them) does not help. 
I have to mention that  there are a lot of mails stored in evolution, and the sheer total number of emails could be the problem (or a catalyst ) for this. However I do not think the number of emails is the only reason, because first a few new emails still get displayed and second this behaviour seems to have started after an upgrade that also updated evolution. 
In order to prove this situation I can provide a few screenshots, and by request the files corresponding to a folder that is not displayed properly.
