Array to String Conversion when importing a ZIP file

[taylordaughtry]

I'm gathering more specific information on replication now, but I thought I'd go ahead and open an issue to see if this is a known-bug just yet! My client was uploading a ZIP file they recieved from the Acclaro team after translation, and after uploading the file ran into the error in the stack trace below!

I think the offending line could be here, but I haven't taken a deep-dive into it just yet.

Stack trace:
