[Bug 103706] krfb crashes after connecting with realvnc viewer

[Jeroen Maris]

Public bug reported:

Binary package hint: krfb

Krfb crashes when connecting with RealVNC Viewer. I can authenticate but
after about 20 seconds it crashes with signal 6 (SIGABRT)

This bug seems to be a duplicate of bug
https://bugs.launchpad.net/ubuntu/+source/kdenetwork/+bug/97639 and bug
https://bugs.launchpad.net/ubuntu/+source/kdenetwork/+bug/39046, but
neither were worked out really clear.

Specs:
- Kubuntu Feisty 7.04 Beta
- Krfb version: 4:3.5.6-0ubuntu9
- RealVNC viewer version: VNC Viewer Personal Edition P4.2.8

I've installed kdenetwork-dbg and debug log is shown below:
