A relevant content I dug from the sylpheed.log file follows:

[18:33:19] ** Sylpheed-WARNING: This should not happen. UNDO_REPLACE_DELETE
[18:33:19] ** Sylpheed-CRITICAL: undo_undo: assertion `undoinfo->action ==
UNDO_ACTION_REPLACE_DELETE' failed [18:33:29] ** Sylpheed-WARNING: This
should not happen. Redo: UNDO_REPLACE_INSERT


Any thoughts?
