This bug was detected = while running docker.el and other packages that depend on tablist [1]. =  Tablist is an extension of tabulated-list-mode that provides the = ability to filter the tabulated list via an expression language. I am = not the author of tablist however the author is aware of this = issue.

In = 27.0.90, tablist is now giving an error when entering its expression = editor.  In the debugger I traced the error to = wisent-total-conflicts in lisp/cedet/semantic/wisent/comp.el line = 2273, in commit 390b4bc1e25fe691548d7ec982eb2f7027fe26a3 [2].  That = commit introduced a mechanism to ignore =E2=80=9Cexpected conflicts=E2=80=9D= via a symbol whose name is constructed on the fly like this:

  =   (format "wisent-%s--expected-conflicts"
 =                     =               =  (replace-regexp-in-string "\\.el$" "" src)

However, this = code doesn=E2=80=99t handle the case where the filename =E2=80=9Csrc=E2= =80=9D is nil.

To reproduce the issue, compile a = grammar like this:

    (require = 'semantic/wisent/comp)
    (require = 'semantic/wisent/wisent)

    (defvar tablist-filter-wisent-grammar
      '(
    =     ;; terminals

        (operand unary-operator = binary-operator or and not)

        ;; terminal associativity & = precedence
        ((left = binary-operator)

      =    (left or)
        =  (left and)
        =  (left not))

        ;; rules
