Hmm, that doesn't look good... Can you try if this is reproducible with the 
development/git version? 

Also, can you reproduce this from the command line, ie.

  $ mu find "date:7d..now" --threads

and, if so, does it make a difference when you run:

  $ G_SLICE=always-malloc mu find "date:7d..now" --threads

Thanks.

Unfortunately, I can't get it to happen again. I tried in Emacs and on the 
command line and on the command line with the git master branch.

Well, okay, let's assume it's gone then. If you catch it again please open (or 
reopen) a bug. Thanks!
