Created attachment 1515348 [details] abrtd output of Xvnc crash. Description of problem: When a root TCanvas is quit with a .q it allways kills the XVnc server. Version-Release number of selected component (if applicable): root-6.14.08-1.el7.x86_64 How reproducible: Every time. Steps to Reproduce: 1. Start a tigervnc server and connect to it. 2. run root. 3. root> TCanvas a 4. root> .q Actual results: It kills the entire XVnc server. Expected results: It should close only the TCanvas Additional info: Note this may be and XVnc thing itself but the strace of root during the .q phase shows a lot of killing from root. If using normal over normal ssh X11 forwarding then things are okay.

Is there any upstream bug for this that can be referenced?
