1.6.9.pre1 執行 gcin -v 會跳出下面一串訊息，而且不顯示 gcin 版本, 也沒跳 Aborted 。

(process:24205): GLib-GObject-CRITICAL **: /home/foo/glib-2.29.90/./gobject/gtype.c:2708: You forgot to call g_type_init()

1.6.8 執行 gcin -v 跳的是：

gcin: version 1.6.8

Aborted

看起來 1.6.9.pre1 為此加了一大堆 gtk_init? 但 gcin binary 應該本來就有 gtk_init, 不知為啥會這樣跳。

把 gtk_init 搬到前面就 ok

因為有些 critical 的 error 沒有 dialog 看不到，所以改成用 dialog 顯示
