I don't think so*.
*All the parameters to XCreateFontSet() seem valid. I suspect my fonts. 
I do think it might be a bug in X (which shouldn't segfault no matter 
what is passed or what weird (and maybe broken) fonts I install). Now I 
have a test case maybe I'll try building that today... (gulp 62Mb of 
source...) ;)

to fix it I turneded off italic in conf.cpp
-    s.font = QFont( commentFamily, normalSize, normalWeight, TRUE );
+    s.font = QFont( commentFamily, normalSize, normalWeight );

It's not the font as such. The xfontset cache code is triggered the 
Qfont bold/italic/size.

On my system if I choose an italic font in designer C++ prefs it 
exhibits the same behaviour and segfaults after typing in /*
This doesn't happen in other Qt applications though - ???

I'll see if I can put a simple Qt test case together.
