Details:

Though this is a really minor bug, but try the following code in GUI:

x = 1;
openvar x;
clear all;


The variable editor will close the variable and puts up 


Variable %d not found.


(See attached png as an example)

I changed the placeholder so that the variable's name shows up in quotes.
Patch included.

As a side note, if someone can explain me when the following line will be used
in the patch ?

return QVariant (QString ("x"));

I don't think we will want to print the statement other than a string
<http://doc.qt.io/archives/qt-4.8/qt.html#ItemDataRole-enum>. (for which
role== Qt::DisplayRole)
