[O] table align error

[thomas]

Hi!

org mode table align (<TAB> key) is broken on my installation.

I'm using the latest version from github:

 Org mode version 9.1.2 (release_9.1.2-154-g99dbca @ /home/thomas/dev/elisp/orgmode/org-mode/lisp/)

This is the message I get when pressing <TAB> on any table:

 org-table-align: Wrong number of arguments: #[(string &optional separators omit-nulls) "ƒ

This is the output from toggle-error-on-debug:

 Debugger entered--Lisp error: (wrong-number-of-arguments #[(string &optional separators omit-nulls) "\203

 [separators omit-nulls split-string-default-separators list notfirst start t 0 nil string-match rexp keep-nulls string] 5 1652423] 4)
  split-string(#("| test\n" 0 6 (fontified nil face org-table) 6 7 (fontified nil)) "\n" t "[     ]")
  org-table-align()
  org-table-next-field()
  call-interactively(org-table-next-field)
  org-cycle(nil)
  call-interactively(org-cycle nil nil)
  recursive-edit()
  debug()
  call-interactively(debug record nil)
  command-execute(debug record)
  execute-extended-command(nil "debug")
  call-interactively(execute-extended-command nil nil)

I can't figure out what's wrong with my installation ... any suggestions would be very helpful!

thank you,

thomas
