File that was causing errors when trying to import it

[Remy Blank]

PluginIssue (​th:TicketImportPlugin or AgiloForScrum or a combination of both).

[robert.buchholz@…]

@rblank, thanks for the CC.

@reporter: This is a collision between the import plugin (or whoever else also monkey-patches the ticket module) and Agilo. Please disable the plugins you do not need (for instance, Agilo also features a CSV import module)
