KDE Version: 4.14.3

Reproducible: Always

Steps to Reproduce:
1. run konsole
2. run mc in konsole
3. navigate to a directory
4. open a new tab

Actual Results:  
The new tab opens in the user's home directory.

Expected Results:  
The new tab opens in the directory where the user navigated in mc.

I investigated the problem - I think.
At the moment I am using the following versions of konsole:
konsole-4.14.3-1.fc20.x86_64.rpm
konsole-part-4.14.3-1.fc20.x86_64.rpm

So I returned back to the last working previous version, which are:
konsole-4.14.2-1.fc20.x86_64.rpm
konsole-part-4.14.2-1.fc20.x86_64.rpm

And now everything works perfectly.
So I downloaded konsole-4.14.3 and konsole-4.14.2 from here (http://download.kde.org/stable/4.14.3/src/konsole-4.14.3.tar.xz)  and here (http://download.kde.org/stable/4.14.2/src/konsole-4.14.2.tar.xz)
I did a directory comparison in Meld, and I found some changes in src/Session.cpp

I think the problem lies on that line where the null reference is returned.
