Virtual folders inhibit quitting

[Uday Reddy]

Trying to quit an IMAP folder, while it still had a virtual folder based on it, gave rise to this error:

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  vm-thread-symbol(nil)
  vm-sort-compare-activity(nil [...])
  vm-sort-compare-xxxxxx([...] [...])
  sort((...))
  vm-sort-messages("activity")
  vm-expunge-folder(t t nil)
  vm-imap-synchronize-folder(t t t nil t)
  vm-save-folder()
  vm-quit(nil)
  call-interactively(vm-quit)

The nil message entry was generated by vm-sort-compare-thread which was called before vm-sort-compare-activity.

The problem was that vm-virtual-quit destroyed threads. It should have been done after save-folder. Fixed it.

[Uday Reddy (reddyuday)]

Problems still persist with regard to quitting virtual folders.

After a folder's virtual folders have been quit, doing pretty much anything with the folder gives rise to arrayp nil error in vm-sort-compare-activity.

This is happening because some message symbols in vm-thread-list have nil for vm-th-messages, even though they have a non-nil vm-th-message. So, vm-thread-root-sym is giving nil in vm-sort-compare-thread. Where is this problem coming from?

Can't reproduce such problems any more.

Problems persist. This error was received today while trying to quit a local folder that has a virtual folder based on it.

False alarm. The session was using VM 8.2.0a.
