Subject: 24.5; disable-theme leaves lingering effects
Date: Sun, 7 Jun 2015 18:09:04 -0700

When I run these commands from a fresh Emacs instance

M-x load-theme RET solarized-light RET
M-x disable-theme RET solarized-light RET
M-x term RET RET

the text background color in term-mode stays what it was set to by the
solarized-light theme. 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.

Note: I don't have Emacs configured to send email, so I copied the
following from the bug-submission utility.
