Do you have virtual keyboard visible when closing dialog?

Hi,
Sdk produces this dump, cannot really figure out the reason? Or what backtrace you mean?

Hi,
I have Canvas in Silica Dialog page but app crashes when leaving dialog page both with accept or cancel swipe. It does not crash always just quite often.
the code:
Canvas {
id: imageCanvas
visible: isImageUrl
width: imgLoader.sourceSize.width
height: imgLoader.sourceSize.height
renderStrategy: Canvas.Immediate
onPaint: {
var ctx = getContext("2d")
ctx.drawImage(imgLoader, 0, 0)
}
}
Image {
id: imgLoader
visible: false
source: isImageUrl ? url : ""
}
The idea is to save image to the gallery in onAccepted if user has selected that option as Canvas has save method which can be used to save image to a file.
And it works fine, but causing app to crash sometimes when leaving Dialog page with cancel swipe. SDK outputs a long crash dump.
