Created attachment 18256 [details] backtrace See backtrace. Firefox bug is https://bugzilla.mozilla.org/show_bug.cgi?id=436689. My system is: Mac OS X 10.4.11, PowerPC G4.
In the current sources, I see: m = CGFontGetHMetricsPtr (font_face->cgFont); /* On OX 10.4, GetHMetricsPtr sometimes returns NULL for unknown reasons */ if (!m) { status = _cairo_error(CAIRO_STATUS_NULL_POINTER); goto FINISH; } which seems to address this very issue.
