[otrs] After upgrading to 2.0.1 from 2.0 beta 4 merging of tickets fails.

While testing after upgrading from 2.0 beta 4 to 2.0.1 I have found a problem. I created two tickets then tried to merge them. I get the following error: Software error: Can't call method "LockSet" on an undefined value at ../..//Kernel/System/Ticket.pm line 3720. For help, please send mail to the webmaster (webmaster@localhost mailto:webmaster@localhost), giving this error message and the time and date of the error.
