--text follows this line--

I'm using Emacs on the master branch so hopefully this is the right
place to report bugs.

My init.el fails on the call to load-path leaving the following
backtrace (from the point load-theme is called):

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  file-directory-p(nil)
  custom-theme--load-path()
  load-theme(havoc-dark t)

Digging deeper, this is caused by the fact that the variable `custom-
theme-directory' has been reset to nil.

This bug is reproducible without any code from my init.el file.

To reproduce

1. launch Emacs with `emacs -Q`
2. M-x describe-variable
3. Enter `custom-theme-directory`
4. Help screen will show that the value of the variable is nil and that
originally it was equal to "~/.emacs.d"

The last point suggests that this variable got changed somewhere.

My current workaround is to manually set this variable in my init.el
file before the call to load-theme.

Happy to help with further debugging! I could also try to provide a fix
if others are too busy, but would require some steering as to where to
look to implement the fix. Also, I would only be able to handle this
after 11 September.
