mod_remote_roster producing errors in the log

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Install prosody and the newest mod_remote_roster module.
2. Connect spectrum2 in gateway mode

What is the expected output? What do you see instead?

 Revision 295ae44b8a01 - continuously produces the error shown below in the prosody log. In addition to outputting the error, prosody consumed high cpu and responded very slowly when connecting up a transport.

 I downloaded and reverted back to c86fc337d56f, and this corrected the issue.
