Created attachment 401466 [details] backtrace I hit this working on bug 492197. I'm making the same call that's made a number of times throughout the file, but I always hit the NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN error. Specifically I try to modify a property of a database statement. I've never encountered this before doing the exact same thing. I haven't been able to reduce to a simple test case, but I can hit it consistently & will post STR with my "test case".

Turns out that I was missing a + in my string concat. So .guid never gets added to the stmt because it's not actually part of the query being passed. So in fact wrapped natives are working exactly like they are supposed to. Maybe if the error was that the property doesn't exist as opposed to not being able to modify it?
