     Type:  defect        |         Status:  new
 Priority:  major         |      Milestone:  1.9.0
Component:  code-mutable  |        Version:  1.9.0a1
 Keywords:                |  Launchpad Bug:
--------------------------+-------------------------
 The new mutable downloader, landed as part of MDMF in #393, has problems
 when asked to download zero bytes: it returns more than zero bytes.

 We have tests in {{{test_mutable.Version}}} to catch this, currently
 disabled.

 This is a blocker for 1.9beta
