I bet you are not running latest release (actually, not even the 
butlast). I discovered this font issue and it was fixed more than a 
year ago, if I remember correctly. That would be  gui 0.25.1
I do not remember actually if the issue is even older.

The issue may affect about any program, even GUI elements.

What versions of gui/back are you using? If you are using Debian's, as 
usual, bug them for an update.

I belive this was a fix needed:
2017-03-31 Fred Kiefer <FredKiefer@gmx.de>

        * Source/NSAttributedString.m: Check for surrogate UTF16
        characters to prevent nil strings when trying to attempt font
        substitution.

But these were the most important fixes:

2016-10-22 Fred Kiefer <FredKiefer@gmx.de>

* Source/GSLayoutManager.m: Don't try to get the advancement for
NSControlGlyph.

2016-09-19 Fred Kiefer <FredKiefer@gmx.de>

* Source/GSFontInfo.m (-fontDescriptor): Simplify creation of font
descriptor. Use only the minimal attributes.
* Source/NSFontDescriptor.m (-postscriptName): Generate PS name
from font name itself.


2016-07-19 Riccardo Mottola <rm@gnu.org>

* Source/NSFontDescriptor.m
If we have no face set, don't append null

I remember the issue being just after a release, making the buggy one 
0.25.0 gui

All "from memory", anything recent is fixed.
