Could also be related to nested event loops caused by colord (see 25/26, 48/49, 95/96) or kauth (see 68).

Can you please check if removing color-daemon related packages avoids the crash?

I removed colord and now I can't get KDE to start at all through an 
XDMCP session.  I get the login/greeter screen and after I sign in the 
session crashes before I get to the desktop.
