bug#5990: 23.1; Cannot type the word 買います

[Erik Mekhsian]

Setting the input method to Japanese and typing the word "kaimasu", then
hitting <space> to cycle through the list of replacement kanji shows
only 改マス and 開マス.  In particular, I expected to see 買います,
although 飼います, 交います, and 支います should be there as well.  This
is the only word I have had this problem with so far.
