[otrs] Small bug on queue naming

Hi, Using 1.2.2 on Linux. We've tried to create some subqueues, and apparently some didn't show up. We narrowed the problem to the main's queue name: if it contains a plus sign (+) it doesn't displays any subqueue in agent view. Example: Queue name: A+B, subqueue A and subqueue B. The subqueues A and B don't show up anywhere. Renaming A+B to AB solves the problem. Regards, Duarte
