OK, I see.
I could reproduce your problem.
I had used the text format with gmail but it needs rich text format with
gmail.
I got the SEGV.

at nsGtkIMModule.cpp:401:
The xulrunner2's nsGtkIMModule.cpp:nsGtkIMModule assigns the wrong offset
== 4292507292.
It's a bug for xulrunner2
http://hg.mozilla.org/mozilla-central/file/42e7f9088975/widget/src/gtk2/nsGtkIMModule.cpp#l877
PRUint32 cursorPos doesn't assign the right value.
Could you file a bug for https://bugzilla.mozilla.org/ ?
I'll add a workaround for ibus zh to port a ibus4 feature.
