I've been seeing this error since the release of 4.4.  It was mentioned 
here on the list, and at the time I thought a fix would surely make its 
way down the pipeline.  Sadly, I haven't seen one, so I found the error 
and fixed it the other day.  If this is causing your users to miss 
replies to tickets, the issue is fairly simple to fix.  The attached 
patch corrects the problem by quoting a variable that has overloaded 
operators, so that it's treated like a string.  I've also sent this 
patch to rt-devel.
