or it could be a user with a bad store.idx file. you could use strace on
the reconstruct -r process to glean which store.idx file it is tripping
on, remove it, and then run the reconstruct -r again.
Or, remove all the store.idx files for every user and run the
reconstruct -r.
Note: Do not BOTH delete the store.idx files AND the mboxlist files. You
get into a chicken and egg situation if you do both at the same time.
reconstruct -m needs to see a store.idx file in a folder for it to be
valid in some cases and reconstruct -r will only rebuild folders that
appear in the mboxlist db files in some cases.
