USFM Converter crash

[lversaw]

USFM Converter .exe crashed when converting folder of Hindi IEV files to docx format. (Image below) It converts the same files successfully to html. The files were on my hard drive but are the same files as found here: https://git.door43.org/STR/hi_iev

testprint.walink.org also fails (HTTP ERROR 500) when converting https://git.door43.org/STR/hi_iev

Yeah we should probably get a better error handler for that
