Comment 1 Nate Graham 2021-03-25 18:38:19 UTC 
Crash is in versioncontrol/updateitemstatesthread.cpp:41, which has this:

const KVersionControlPlugin::ItemVersion version = m_plugin->itemVersion(item);

Is this image in a git repo or another kind of source control system? Do you have dolphin's source control integration plugin installed?

Comment 3 Samuel Rüegger 2021-04-09 05:19:42 UTC 
Sorry for my late Response.

The Image was not in a GIT Folder. But in a Dropbox Sync Folder with Running Dropbox Client and installed Dolphin Dropbox Plugin.

I'm not sure if Dropbox is using Git or some form of version control system.
Comment 4 Nate Graham 2021-04-09 14:51:38 UTC 
Ah, it's probably using the same versioning code for dropbox, which also does versioning.

Could you attach the file, or any HEIC file that can be used to reproduce the crash?
Comment 5 Samuel Rüegger 2021-04-09 15:03:19 UTC 
This time I respond faster ;)

I can't attach the image, but would have to edit it as it is around 48MB.

But just noticed that the problem no longer occurs.

When I open the image now, the image opens and Dolphin does not crash.
Comment 6 Nate Graham 2021-04-09 16:54:40 UTC 
Wow that's a big image.

Maybe something deeper in the stack fixed this. Let's re-open if it happens again.
