我們需要一些 debuginfo 套件
請確認已啟用 debug 套件庫

#  zypper in libexpat1-debuginfo-32bit fontconfig-debuginfo-32bit

沒錯，即使是 64 位元的系統，您仍需要 32位元的套件

再次執行 gdb

您可以看見某些 fonconfig 的設定造成了程式區段記憶體錯誤
在 #7 ...   "/etc/fonts/conf.d/11-suse-hinting.conf"
請移除檔案 /etc/fonts/conf.d/11-suse-hinting.conf

# rm  /etc/fonts/conf.d/11-suse-hinting.conf

再次執行 gdb 您也可以發現 /etc/fonts/conf.d/65-fonts-persian.conf 也需要刪除

# rm  /etc/fonts/conf.d/65-fonts-persian.conf

字體看起來不錯，不再需要取代 libQT*
非拉丁字元也可以正確顯示

也有些問題待解決:
1. 有些圖片看不見

2. 幾乎所有跳出視窗中的連結都沒辦法按一下就連結到目標
您必須在連結上按右鍵，選擇 "open in new window" 以連結到目標

3. flash 無法運作
4. 有時會崩潰...
