Bug 193833

I think I have fixed this bug some days ago. 

Just to be sure: If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? 
You need to install the "kdelibs5-dbg" package.
Thanks

How did you fix it?
I can't even run kate now. 
And the backtrce crushes too.
------------------------

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash

I fixed it in the development branch of the KDE code. The fix should be in KDE4.2.4 and 4.3. 

Please install the "kdelibs5-dbg" package to get a better backtrace. Thanks

Here is what I have after installing kdelibs5-dbg.
This is when I try to run kate from terminal. (It can't be open at all from K-menu.)

Application: Kate (kate), signal SIGSEGV

Also I think that bug is about opening saved sessions, not just "index.html" 
In principal I can run kate when I specify filename to open:

~$ kate Web/index.html &
[2] 5873
~$ Calling appendChild() on a null node does nothing.

Indeed, it is the same crash I fixed some days ago, the fix will be on KDE4.2.4 and 4.3
