error on first steps with LTK

[Ulrich Vollert]

Hello,

I am trying to make a text widget:

(defun hello()
  (with-ltk ()
    (let* ((tx (make-instance 'text )))
      (pack tx))))


But I get an error (here the messages by slime):

too many colons in "07"

  Stream: #<TWO-WAY-STREAM
            :INPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 16" {1005CE4193}>
            :OUTPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 9" {1005CE45B3}>>
   [Condition of type SB-INT:SIMPLE-READER-ERROR]

Restarts:
 0: [SEND-TO-DEBUGGER] Send condition to the debugger
 1: [ABORT] Abort handling Tk event
 2: [EXIT] Exit Ltk main loop
 3: [RETRY] Retry SLIME REPL evaluation request.
 4: [*ABORT] Return to SLIME's top level.
