Describe the bug

Utilising Spectacle's "Active Window" mode on KSnip's GUI causes a segmentation fault.

To Reproduce

1. Invoke gdb ksnip (this reproduces outside gdb, too):

   

2. Invoke spectacle --new-instance.

3. Utilise the "Active Window" mode on KSnip's GUI:

   

Expected behavior

It should not crash.

Desktop

1. OS

   kernel-6.14.4-300.fc42.x86_64

2. Distribution, in the case of Linux

   PRETTY_NAME="Fedora Linux 42 (KDE Plasma Desktop Edition)"
   CPE_NAME="cpe:/o:fedoraproject:fedora:42"

3. Window system, in the case of Linux

   kwin-wayland-6.3.4-3.fc42.x86_64

4. KSnip version

   ksnip-1.10.1-7.fc42.x86_64

5. How did you install KSnip?

   sudo dnf5 install --refresh -y ksnip

Additional context

My trace from gdb is undermentioned:
