You would have to give me a precise recipe to reproduce the failure.
Note that debugging widgets is a real pain, that's why I usually try to
avoid it.  You could try to edebug `widget-default-value-set' (according
to Richard there's a bug) and see for yourself.  Be sure to cancel the
timer before and invoke `refresh' manually.  It might be worth to edebug
the `widget-field-...' functions as well.

Does the character of the problem change when you set
`widget-field-add-space' to a non-nil value?  Does setting
`widget-field-use-before-change' to nil affect the problem?
