If it doesn't, the cause for that would need to be found out.

As we haven't run to the problem you have, unfortunately you need
to help us to find the cause for it (i.e. way to reproduce it)
if you want it fixed.

If you have some time to test this, maybe you could strace crawler
overnight to see whether anything triggers it to go non-idle?
Before & after that you should check from "top" that it's not using CPU.

There could be other changes / reasons for it, maybe you did
some other change during the same day?  Or maybe you inserted a memory
card which triggered something in crawler (like the one MMC mentioned
in Bugzilla which had "millions" of folders on it that had been created
by accident)?
