Description Mihaela 2020-02-22 15:26:55 UTC

Application: kwin_x11 (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-40-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:

I was trying to import photos from a camera in DigiKam. I have a collection setup on a removable drive. Importing there worked on my previous OS. Now I'm new on KUbuntu 19 and I can't get it to work on the removable media. I had to import onto the local disk instead in the end. 

- Custom settings of the application:
I didn't have the removable media set to automount when I first started DigiKam, but I have enabled that since I started and failed the import of the photos. The disk was mounted before I tried the download, and I could see the path to the disk in the Collection settings (/media/username/longdevicename/Photos)

The crash happened when I closed DigiKam, it was stable up to that point.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted

Comment 1 Vlad Zahorodnii 2020-03-19 10:28:36 UTC

Most likely, this is a duplicate of bug 368847. If you're able to reproduce this crash, could you please install debug packages for kwin and attach a new backtrace when the crash happens next time?

Comment 2 Vlad Zahorodnii 2020-03-19 10:29:06 UTC

Also, note that 5.16 is no longer maintained by KDE.

Comment 5 Mihaela 2020-05-02 22:12:53 UTC

I have in the meantime moved from Plasma to GNOME, and I haven't noticed any crashes. 

Kwin did crash a lot for me related to some Plasma animations (reported), unrelated to digiKam, so maybe this bug is related to Kwin. 

But there is one other difference that may be related: in Plasma KDE the remote media path inside digiKam was /media/username/longdevicename/Photos/ but the same location now on GNOME is /mnt/longdevicename/Photos/. 

When setting up the collection in GNOME I chose the removable media option, but digiKam still added it under Local, I guess it matters if the device is automounted? 

I haven't removed KDE yet so I can login back if you'd like me to run backtrace again. I installed kwin-dev package. 

Is it safe for me to do that? I don't want that to affect my collection in a bad way.

I'm not an expert, but it should be fairly safe to do that.

Comment 7 Vlad Zahorodnii 2020-05-05 05:47:54 UTC

Settings the status of the bug report back to needs NEEDSINFO BACKTRACE.
