I had the exact same experience; I didn't see any bugs filed about that on the GTK-Wimp SourceForge site. A Google for "gtk-wimp" nt4 found: http://www2.arnes.si/~sopjsimo/gimp/faq.html which says: o I installed Gimp 2.0 on Windows 9x/ME or NT 4, and I'm getting a lot of messages saying ** (gimp-2.0.exe:4294830849): WARNING **: Couldn't load font "MS Sans Serif 8" falling back to "Sans 8". What should I do? o You have two options: o Go to Control Panel->Display properties->Apperance tab, and set all fonts to Tahoma (or any other TrueType font). o Uninstall GTK+ 2.2.4, then re-install it without the GTK-Wimp component. and a Google for "gtk-wimp" "ms sans" found http://mail.gnome.org/archives/gtk-app-devel-list/2004-January/msg00443.html which says: From: "Rastatter, Ken (OH32)" <Ken Rastatter Honeywell com> To: "'gtk-app-devel-list gnome org'" <gtk-app-devel-list gnome org> Subject: RE: Error selecting font with gtk-wimp engine and win98 Date: Fri, 30 Jan 2004 09:23:11 -0700 Goran Rakic wrote: > If I choose some other font (Tahoma) in Display properties > instead of default MS Sans Serif, application is working > as it should. MS Sans Serif is a .fon file and not TTF font, > maybe that can be a problem? You are correct. Pango can't deal with bitmap (.fon) fonts. Back in November, 2003 I submitted a GTK-Wimp bug report to http://www.sourceforge.net/projects/gtk-wimp about this issue: [ 840287 ] Win98 warnings: Couldn't load font "MS Sans Serif 8" Since this is technically a Pango issue and not a GTK+ or GTK-Wimp issue, the GTK-Wimp bug was closed. However, I've unable to find a Pango bug report about it. -- Ken Rastatter so it appears that the problem is that, at least in NT 4 (and perhaps in some older versions of Windows OT, as I've seen this mentioned for W98 and possibly W95), the MS Sans Serif font is a bitmapped font, and Pango can only handle scalable fonts. The bug in question is at http://sourceforge.net/tracker/index.php?func=detail&aid=840287&group_id=76416&atid=547655 which says I think these warnings are generated because Pango can only work with TrueType fonts, not bitmapped fonts such as MS Sans Serif. Out of the box, Windows 98 uses MS Sans Serif as the Caption Font, Menu Font, Status Font and Message Font. To make some of the warnings go away, you can use "Control Panel -> Display -> Appearance" to change the Menu Font to a TrueType font. These warnings do not appear under Windows 2000 because out of the box it uses the Tahoma TrueType font. Presumably W95 also uses MS Sans Serif; we should probably disable GTK-Wimp for W95 and W98, and, unless WMe uses Tahoma or some other TT font for those system font purposes, WMe as well, and also disable it for NT 4.0.
