tries to dereference a null pointer. This trivial patch checks that string!=NULL before dereferencing it.
After that correction, dtcm is working with the ja_JP locale. Some problems remain:
* The year view of the calendar remains blank * The month view shows '7n' instead of the Kanji for month* The Kanjis of some days in the month view are replaced by alphanumeric characters.
