I'm running into errors when attempting to run flymake-show-diagnostics-buffer. If run after I've enabled line numbers via global-display-line-numbers-mode, I get the following stack trace:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
flymake--diagnostics-buffer-entries()

funcall-interactively(execute-extended-command nil "flymake-show-diagnostics-buffer" "flymake-show-diagnostics")
call-interactively(execute-extended-command nil nil)
command-execute(execute-extended-command)
Once this has been thrown once, running flymake-show-diagnostics-buffer
works properly. The only thing in my config file is
(global-display-line-numbers-mode).
To repro:
emacs -Q
C-x b *scratch*
M-x global-display-line-numbers-mode
M-x flymake-mode
M-x flymake-show-diagnostics-buffer
