Application: kate (3.13.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.2
Operating System: Linux 3.2.0-61-generic x86_64
Distribution: Ubuntu 12.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I have a text file which, when I try to press enter to move the first line below, Kate crashes.

It happens every time, and Dr. Konqi only installed some of the necesary debugging symbols. I intalled as much "dbg" packages I realized were necesary.

Dr. Konqi installed
kate-dbg

And so far, I installed:
kdebase-runtime-dbg{a} 
kdesdk-dbg
kde-workspace-dbg
libqt4-script-dbg
libglib2.0-0-dbg
libqt4-xmlpatterns-dbg 
qt4-bin-dbg

which at least improve the "qualification" made by Dr. Konqi, but it seems they aren't enough. Since it happens every time, please tell me which packages I'm missing and I'll install them.

More info:
Kubuntu 12.04.4 x86_64, with KDE 4.13.0 just installed today
AMD Phenom X3 8450
NVidia 9500 G with 331.20 driver

The crash can be reproduced every time.
