#5681: infinite input area auto resizing, pidgin hangs.

 When input complex characters such as korean or chinese using scim, pidgin
 falls into infinite loop when input area auto-resizing occurs.

 Here is a test scenario:
  1. Setting SCIM language to Korean or Chinese.
  2. Fill those complex characters(not ascii) in pidgin's conversation
 input area to be auto-resized.
  3. Infinit auto-resizing, input area widget shakes.

 To see what happens, I attached to the process when auto-resize occurs. It
 looks like gtkconv.c:resize_imhtml_cb() function is problem. Once resize
 occurs, resize_imhtml_cb() is called infinitely so it makes pidgin hang.

 Attaching manually gdb-traced results. I put display of meaningful values
 for each continue-stop that may helps understand why.
