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):
Steps to Reproduce:
1. Start a tigervnc server and connect to it.
2. run root.
3. root> TCanvas a
4. root> .q
It kills the entire XVnc server.
It should close only the TCanvas
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.

backtrace of the Xvnc crash.
Is there any upstream bug for this that can be referenced?
A workaround is available if backing store is disabled within Xvnc
