This is IMAP related.

The inbox has a message filter to move mails with a specific subject (e.g.
[CREW]) to a particular folder. We'll call this folder "crew". I was testing the
filters and it moved all messages to that folder. I then wanted to add a second
filter so I moved all the messages from "crew" back to "inbox". For some reason
the messages where not there, clicking around on different folders showed the
msgs back in the "crew" folder. I created a new profile to test this behaviour.
It seems that messages moved to a folder, where a message filter has been
specified to move messages to a folder, will re-move the messages back the
folder. For some weird reason this only happens when moving UNREAD messages. ie.
the mail filter doesn't seem to want to move them back to the "crew" folder
(possibly because it thinks the mail is not NEW).

IMO, moving (unread) messages to a folder that has messages filter, from a
folder where a message filter would move mail to, should no execute the mail
filter. I hope you're still with me .. i'll try to be as specific as possible in
the steps to reproduce

Reproducible: Always
Steps to Reproduce:
1. add imap account
2. create folder to store moved mail, e.g. crew
3. create a message filter which moves mail with specific subject to that
folder, ie. Subject contains [crew] move to crew folder.
4. check that mail filter works by doing a "Run Filter Now" (I assume you have
relevant messages to move in yur INBOX)
5. All your unread messages, moved by your filter, are now in your crew folder
6. selected the crew folder and select all messages (ctrl a), move them back to
inbox
7. you will see a "moving messages to inbox" in status bar, and the inbox will
now show X unread messages.
8. select INBOX (unread messages disppears) and the crew folder appears to have
X unread messages again, no messages can be found in INBOX, your crew folder has
all the messages again

Actual Results:  
INBOX (message filter)
`crew folder

INBOX moves unread messages to crew
manually moving unread messages back to INBOX will automatically execute message
filter and re-move the messages to crew folder.

Expected Results:  
Moving unread message from crew->inbox (which has a message filter to move NEW
mail to crew) should not move mail.

just to clarify:

Expected Results:  
Moving unread message from crew->inbox (which has a message filter to move NEW
mail to crew) should not move mail back to where it came from if they are unread. 

Isn't unread != new mail then?

What filter log says after step 7? How about after step 8?
Message filtering is executed on "Clicking Inbox" when IMAP, isn't it?

Filter log when I moved 3 messages back from subfolder to INBOX:

(the folder is actually JIRA, not crew), I was giving a fake example before, in
other words "crew" folder from comment #0 == JIRA folder in filter log.

It seems indeed that the message filter is executed when clicking on the inbox,
but in some way i would expect new mail !- unread mail.

In the end I end up with my messages back in my original JIRA folder. I have to
mark them unread to move them to my INBOX so that the message filter doesn't
kick in.
