The next mod listed in registry.json is KSPFrenchTranslation, which has a "name" value of "KSP 1.3 Full Game French Transaltion {BETA}". Hmm, those curly braces make it look like a malformed string format parameter. Maybe someone's passing that string where a format string is expected?

... Yup. RaiseMessage has a format/args parameter pattern, and is used that way throughout CKAN, except in CmdLine.Available.RunCommand, where the return value of a String.Format call is passed as the format parameter, which means trouble if any of the args contain curly braces:

CKAN/Cmdline/Action/Available.cs

Lines 30 to 33 in 1fe5997

	foreach (CkanModule module in available)
	{
	user.RaiseMessage(String.Format("* {0} ({1}) - {2}", module.identifier, module.version, module.name));
	}

The attached change fixes the issue in my testing.
