This bug is still present.
It looks like solarized still sets the obsoleted variables
term-default-fg-color and term-default-bg-color, but still, the bug is
in custom.el and it's related to Bug#21355.
Here's a recipe:
Save this theme into test-bug20766-theme.el, and arrange to load it.
(deftheme test-bug20766)
(custom-theme-set-variables
'test-bug20766
'(test-option 'foo))
(provide-theme 'test-bug20766)
emacs -Q
M-x load-theme RET test-bug20766
test-option is not yet known, so custom stores the theme setting under
the saved-value property of test-option.
M-x disable-theme RET test-bug20766
The saved-value property should be nil, because the theme setting is no
longer relevant. However, it's still ('foo).
Then eval the following defcustom:
(defcustom test-option 'bar "..."
:type 'symbol
:group 'emacs)
M-: test-option ==> foo, which is wrong.
In the original recipe, that is how term-default-fg-color and
term-default-bg-color get the solarized theme setting after loading
term.

A very similar invocation does not have this behavior: M-x term RET RET C-c k RET yes RET M-x load-theme RET solarized-light RET M-x disable-theme RET solarized-light RET M-x term RET RET i.e. If term mode gets to run before loading the theme, no bug. the 'solarized-light' theme was installed from melpa via M-x package-list-packages, and is upstream at https://github.com/bbatsov/solarized-emacs. I'm not certain whether the behavior is specific to that theme or not. What I have observed is that there seems to be an interaction with the variables term-default-fg-color and term-default-bg-color. They start as :not-bound. Solarized light sets them to some value when loaded, and resets them to :not-bound when unloaded. However, term mode also sets them when started (both to 'nil) and seems to never reset them to :not-bound.
