QFileDialog GetOpenFileName 使用上造成崩溃

[wrzfeijianshen]

代码如下. 运行后导致程序崩溃,但GetExistingDirectoryp 目录就没有问题,而打开文件有问题

fileFialog := qtwidgets.NewQFileDialog1(this.MainWindow, "打开文件", path, "*.*")
str := fileFialog.GetOpenFileNamep()

写了个简单的测试，竟然不崩溃。可能还需要更长一点的代码
OS: linux
qtinline && qt.go: 5.12

大体上是这样子的,操作如下: 先窗口大小拉大后, 打开文件成功之后,再把窗口的大小,拉大,缩小.循环往复几次,程序就崩溃了
程序 在上,崩溃日志在下边

package main

import (
	"fmt"
	"os"

	"github.com/kitech/qt.go/qtgui"
	"github.com/kitech/qt.go/qtrt"
	"github.com/kitech/qt.go/qtwidgets"
)

func main() {
	app := qtwidgets.NewQApplication(len(os.Args), os.Args, 0)

	mw := NewUi_MainWindow2()
	mw.MainWindow.Resize(200, 200)
	btn := qtwidgets.NewQPushButton(mw.MainWindow)
	btn.Resize(100, 50)
	qtrt.Connect(btn, "clicked(bool)", func(bool) {
		fmt.Println("点击了")
		path := "."
		fileFialog := qtwidgets.NewQFileDialog1(mw.MainWindow, "openfile", path, "*.*")
		str := fileFialog.GetOpenFileNamep()
		// fileFialog.Close()
		fmt.Println(str)
	})
	mw.MainWindow.Show()

	if false {
		f1 := func(painter *qtgui.QPainter) {
			painter.SetPen2(1)
			painter.DrawLine2(10, 10, 100, 100)
		}
		mw.Centralwidget.InheritInitPainter(f1)
	}

	app.Exec()
}
