I also observe this behaviour, mostly when walking through a very large
IMAP folder, reading the mails. Then sometimes evolution becomes
unresponsive for a few seconds. I cannot observe this every time.

I guess, I know what's maybe causing this: I prefer to get the mails
every 5 minutes. As longer as evolution runs, it needs more and more
time to fetch the mails - not because the count of mails it has to fetch
increases. It simply gets more and more unresponsive when fetching the
mails. Say in the first hour, it needs 1 second, when I press the button
to fetch the mails. After running maybe 4 hours it becomes unresponsive
for at least 10 seconds when I press the button to fetch the mails.

And maybe this process, that fetches the mails every 5 minutes, is
causing the unresponsive times during walking through my folders too. I
hope, you understand, what I want to say :) The issue is really a bit
obscure.

@Ross: Maybe you observe the same? The next time the issue occurs for
you, could you check, if the system also gets unresponsive, when you
press the button to fetch the mails?
