Is anyone else seeing these errors when closing some, but not all, tickets?  <br><br>

Reload!</span></p>

The ticket closes successfully but the agent is left with a server error.<br><br>I already have a bug open for this,<a href="http://bugs.otrs.org/show_bug.cgi?id=6055"> http://bugs.otrs.org/show_bug.cgi?id=6055</a>, but am wondering if anyone else has a workaround.<br>
