Taking a photo with timer set to anything other than 'Immediate' fails

[garycmartin]

Testing Record 91 on an XO-1 (build os21). Setting the timer to anything other than 'Immediate' and clicking the record button fails to take a photo and triggers the below traceback. The record button disappears and you need to Stop and resume Record to get it back:

/home/olpc/Activities/Record.activity/record.py:727: GtkWarning: Using Cairo
rendering requires the drawable argument to
have a specified colormap. All windows have a colormap,
however, pixmaps only have colormap by default if they
were created with a non-NULL window argument. Otherwise
a colormap must be set on them with gdk_drawable_set_colormap
  ctx = pixmap.cairo_create()
