GTK:ACCEL-GROUPS-FROM-OBJECT

Hi Espen,

While trying to make multiple selection of a tree more intuitive and
predicatable, I came across this problem:

(gtk:accel-groups-from-object (make-instance 'gtk:window))


Error in function FIND-APPLICABLE-TYPE-METHOD:
   No applicable type method for READER-FUNCTION when call width type specifier ACCEL-GROUPS
   [Condition of type SIMPLE-ERROR]

Restarts:
 0: [ABORT] Return to SLIME's top level.
 1: [ABORT] Return to Top-Level.

Backtrace:
  0: (FIND-APPLICABLE-TYPE-METHOD READER-FUNCTION GTK::ACCEL-GROUPS T)
  1: (READER-FUNCTION GTK::ACCEL-GROUPS :REF :GET)
  2: (GLIB::MAP-GLIST LIST
                      #<Function IDENTITY {10201F29}>
                      #.(INT-SAP #x00000000)
                      GTK::ACCEL-GROUPS
                      ...)
  3: (GTK:ACCEL-GROUPS-FROM-OBJECT #<GTK:WINDOW at 0x80F23F0>)
  4: (SWANK::EVAL-REGION
      "(gtk:accel-groups-from-object (make-instance 'gtk:window))
     "
      T)

Could you please look into this?

Best,
