I have created a package for your appimage and I'm encountering the same problem when using the appimage.
Inserting an image results in a seg fault.

"Inserting an image results in a seg fault" should read "Pasting an image results in a seg fault". My apologies for the duplicated text by Comment 2. Is it possible to edit comments? I don't see an option to do so.

I cannot reproduce this issue on Windows. It seems like it is something linux-specific.

Ralf, could you tell, do you use X11 or Wayland?

Hi Dmitry,

I'm still a X user. 

From comment 1:
$ grep \ Driver /etc/X11/xorg.conf
        Driver     "modesetting"

A copy of comment 2:
$ pacman -Q xf86-video-intel
xf86-video-intel 1:2.99.917+923+gb74b67f0-2

And FWIW additional info. CPU with integrated GPU:
$ hwinfo --cpu | grep Model | sort -u
  Model: 6.191.5 "13th Gen Intel(R) Core(TM) i3-13100"

Kernel:
$ uname -r
6.10.0-arch1-1

Kernel parameters:
$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-linux root=/dev/disk/by-label/m1.archlinux ro threadirqs ibt=off

Regards,
Ralf

I can reproduce this with the 5.2.3 appimage. I also see

krita(3726868)/(default) kis_assert_common: SAFE ASSERT (krita): "!nodes.isEmpty()" in file /home/halla/dev/5.2/libs/image/kis_layer_utils.cpp, line 1599

And lots of

krita(3727282)/(krita.general) KisToolRectangleBase::endStroke: Unexpected tool event has come to endStroke while being mode 0 !
krita(3727282)/(krita.general) KisToolRectangleBase::endStroke: Unexpected tool event has come to endStroke while being mode 0 !

I cannot reproduce the crash in gdb, though, so I don't have a backtrace.

ctrl-a; ctrl-c; ctrl-tab; ctrl-v doesn't paste anything, even though the paste is enabled.

(Oh, and trying to right-click in the layerbox to paste the clipboard doesn't toggle the menu unless I click on an existing layer.)

As Freya pointed out on the forums, this seems to be related to bug #490843. Trying to paste Krita layer contents into a document with no actively selected layer leads to the segfault.
I can consistently get the crash so long as I can get to a state with no active layer selected (by switching tabs)
The crash never happens so long as I ensure a layer is selected before pasting.

Thanks Freya and Ralek!

I can confirm that this bug has the same cause as bug 490843 and is fixed with its fix.

Make clip-pasting code a bit more robust

We should check if the active layer is actually non-null when pasting
a mime-data. It is possible that no layer is selected, but it we still
shouldn't crash because of that.
