Comment 1 caulier.gilles 2017-04-05 19:58:11 UTC

The crash appear when thumbnails are extracted for camera.

I see QtAV called. You have video files in your memory cards. Right ?

I'm not sure if the problem come from the video media. Which kind of video type mime do you use exactly ?

If this video file are imported on your computer by another way than DK Import tool, can you see any video thumbnails generated in album icon view ?

Gilles Caulier

Comment 2 Maik Qualmann 2017-04-06 18:17:43 UTC

The function getCameraThumbsCtrl() is only connected in the MapWidgetView. The video thumbnailer is currently unused. I have no explanation for this crash at the moment.

Comment 3 Maik Qualmann 2017-04-06 18:25:59 UTC

For me, it looks as if it crashes inside Qt. Maybe a problem with Qt-5.8.0 and signal / slots connection?

Maik

Comment 4 caulier.gilles 2017-04-06 19:14:04 UTC

If it's Qt5.8.0 problem well give a try to 5.6.0 beta of AppImage for Linux which is complied with Qt 5.7.1.

Comment 7 Martin 2017-06-23 20:24:06 UTC

So far, I was not able to reproduce the bug with the current version. I am marking the bug as fixed and will reopen it when necessary.
