Comment 1 for bug 673931

One thing more that may help :
I use some filters to sort any emails and move them in some other directories
When the issue is on then the messages are not filtered anymore and go down within the inbox directory.
If I try to force the filter, it doesn't work and the message keep on inbox then, in this case too, I have to restart TDB to get it working.
All my filters are setted with "check the message after sort or execute by hand" (this is a translation from french, it might be a bit different in correct english)
