KisMediatorSingleTon and closing Krita

[Boudewijn Rempt]

For some time now, I either cannot close Krita at all (the process keeps 
hanging), or I get a crash with a long backtrace (see below). Am I the only 
one to have these problems -- i.e., is it something local to my computer, or 
is it more widespread, and, more importantly, does anyone know what's going 
on?
