[m17n-list] m17n-im-config crash under zh_CN locale

[Daiki Ueno]

Hi,

Under zh_CN.utf8 locale, I got a crash when double-clicking "Other" ->
"unicode" on m17n-im-config dialog (backtrace attached).

The bug was originally reported to ibus-setup-m17n, which shares the
code with m17n-im-config:
https://bugzilla.redhat.com/show_bug.cgi?id=836397

Program terminated with signal 11, Segmentation fault.
