--- Comment #1 from Hans Leidekker hans@meelstraat.net 2012-06-19 14:52:51 CDT --- MsiDatabaseImportW should do proper input validation instead of crashing, but your idt files are not correctly formatted. They have a literal '\t' where there should be a tab. Probably because you're using a different shell than the author of build-winemono.sh.
