Error message with number columns

[Noughty]

I get this error message then trying to edit column Pages (floating point numbers):

calibre, version 0.8.4
ERROR: Unhandled exception: <b>TypeError</b>:QDoubleSpinBox.setValue(float): argument 1 has unexpected type 'NoneType'

Traceback (most recent call last):
File "site-packages\calibre\gui2\library\delegates.py", line 291, in setEditorData
TypeError: QDoubleSpinBox.setValue(float): argument 1 has unexpected type 'NoneType'

I made another column for pages (integral) and I still get error message:
calibre, version 0.8.4
ERROR: Unhandled exception: <b>TypeError</b>:QSpinBox.setValue(int): argument 1 has unexpected type 'NoneType'

Traceback (most recent call last):
File "site-packages\calibre\gui2\library\delegates.py", line 291, in setEditorData
TypeError: QSpinBox.setValue(int): argument 1 has unexpected type 'NoneType'


This happens when column is empty and I want to add value to it (not in metadata edit window). I can add value fine, but I always get the error message. Unless there already was a value and I am changing it.

That bug was fixed in source on 4/June. The fix is in 0.8.5
