IBUS crashes when pressing Shift-Alt-M in Anthy

[Christoph Schmidt]

When I switch IBUS to Anthy (Text is converted to Hiragana) and press Alt-Shift-M, IBUS crashes.
(The reason I pressed this combination is that in Anki, this combination is used for some function. However, the crash
does occur when typing into any program.)

Reproduction:
1) Go to any application (terminal, libreoffice writer, etc.)
2) Switch to Japanese input with CTRL-Shift
3) Type Hiragana (works!)
4) Press Shift-Alt-M
5) Type Hiragana (only Romaji appears)
