[Mikael Relbe]

WrongTrac, this is a PluginIssue, and I guess it concerns one of ​AgiloForScrumPlugin or ​AgiloTicketReportPlugin.

[Martin Häcker <martin.haecker@…>]

@reporter: This is a strange issue, as the backlog for that sprint seems not to have been created (?) Could you please join our support google group to help us resolve the issue? (More details at AgiloForScrum).

@mrelbe & rblank: thanks for the wrangling! :)
