Description of problem:
In the F10 version the virtual folders feature doesn't work reliably. Here are a few examples,

The Unread mail folder will indicate that there are unread messages but when you look in the folder there is nothing in it.

Other virtual folders will indicate that there are unread message (as indicated by the Bold title and an unread message error count), but if you look in the folder there will be no new messages.

When you convert a database from and older version of Evolution it will indicated that there are thousands of unread messages in the various virtual folders.

Version-Release number of selected component (if applicable):2.24.3




How reproducible: 100%


Steps to Reproduce:
1. Just keep Evolution open and wait for new mail
2.
3.
  
Actual results: Sometimes the messages appear in the Unread folders and sometimes they don't.  Exiting and restarting Evolution will usually fix the problems.


Expected results:


Additional info: This is an F10 problem only, the version on F9 doesn't have this issue although the F9 version crashes on occasion.
