Import Snapshot Broken in 4.5.3?

[Scott Rossi]

Houston, I think we have a problem.

This script works in LC (Rev) 4 OS X but generates an error in 4.5.3:
  import snapshot from rect (rect of the selobj) of the selobj

Message execution error:
Error description: value: error executing expression
Hint: import snapshot from rect (rect of the selobj) of the selobj

Other variations also fail, ie:

  import snapshot from rect (rect of btn 1) of btn 1

Message execution error:
Error description: value: error executing expression
Hint: import snapshot from rect (rect of btn 1) of btn 1


  import snapshot from rect (10,10,100,100)

Message execution error:
Error description: value: error executing expression
Hint: import snapshot from rect (10,10,100,100)

Can anybody else confirm this?  Is it just me?  If not, this seems like a
pretty important issue.
