JEmacs, ELisp interaction - trouble

[Yaroslav Kavenchuk <kavenchuk at jenty dot by>]

kawa from SVN head

I typed in ELisp interaction mode
(+ 1 1)
I then pressed 'Enter' - the cursor was moved to the beginning of the 
next line and any result was not displayed.

When I clicked "Enter" again:

Exception in thread "AWT-EventQueue-0" 
java.lang.IllegalArgumentException: Text must contain at least one 
character.
