Chinese Conversion is a useful tool to convert between Traditional Chinese and Simplified Chinese, but it crashes within the 4 series.
Steps to reproduce:
1. Copy "臺灣 is Taiwan." and paste it to Writer
2. Select Tools > Language > Chinese Conversion, and press OK button.
3. Writer crashes
Chinese Conversion should work fine even when there are some Engilsh words in the text beside Chinese characters.
