When i editing text in Book View and switch in Code View, all Non-breaking space are doubled.
I think this bug is since 0.8.3

Example:
Original

<p>Text1&nbsp;Text2&nbsp;Text3</p>

after editing any Text in Book View an switch in Code View

<p>Text1&nbsp;&nbsp;Text2&nbsp;&nbsp;Text3</p>

i attached epub with example.

OS: aptosid x86_64 (based on Debian unstable)
Sigil 0.8.4 (from DiapDealer)
