Description bertine 2017-07-28 10:09:55 UTC

Whenever Windows Explorer tries to preview .kra files in thumbnail, I get a COM Surrogate crash. 

Oddly enough, windows does display a preview thumbnail after I click away the crash message.

However, it does this with every single .kra file in the explorer window.

Seeing as I'm currently working on a project with a ton of .kra files, it's getting seriously annoying.

This has occurred at least in all 3.x.x versions.

Hi Bertine,

I'm afraid I cannot reproduce this on my surface pro, so there must be something else going on as well... Could you try to install the shell extension with its own installer (https://download.kde.org/stable/krita/kritashellex-1.2.3.0-setup.exe) and check whether that makes a difference?

Created attachment 106915 [details]
This is a file that causes a COM Surrogate crash on my system

It was an autosave, but other autosaves don't cause the crash.

Hi Boud,

Unfortunately, installing the shell extension didn't help.

It seems it's not all .kra files that cause the COM Surrogate crash. In an earlier post I attached a file that caused it to crash.

Please try to install this new version, the bug should be fixed:

https://github.com/alvinhochun/KritaShellExtension/releases/download/v1.2.4/KritaShellExtension-v1.2.4-setup.exe

(This will be included in the final Krita 3.2.0 release.)

Hi Alvin,

Brilliant, that seems to have fixed the issue!
