Kerblooey in CDE drag -n- drop

This requires a Mule XEmacs and a dtterm capable of displaying Japanese. Select a string of text displayed in the dtterm by left mouse click such as the string `だったら半角カタカナ' in mule-canna.c. Release the left mouse button and then left mouse click again to drag the text into any convenient XEmacs/Mule built with CDE drag -n- drop. Fatal error: assertion failed, file insdel.c, line 364, VALID_CHARPTR_P (ptr) Fatal error (6). ... This kills both 21.1 and 21.2 although the message is different in 21.1. I suggest making the default for CDE drag -n- drop be off until this bug is fixed. -- I protest the NATO war in Yugoslavia.
