No, these are different. This is a crash and that issue was a rendering problem.
Celluloid doesn't crash for me on my Plasma install.
Unfortunately, that stack trace isn't very helpful because you don't have debug packages (which is why you see a lot of 'n/a'). From what is there it looks like a crash in the Vulkan drivers and GTK.
I recommend installing debug packages, creating a new backtrace and then reporting the crash to the Celluloid developers here, with the new backtrace.
The debug packages you need can be installed with
sudo eopkg it vulkan-dbginfo libgtk-4-dbginfo python-gobject2-dbginfo celluloid-dbginfo
Since this doesn't look like an issue with the packaging of the software, this is likely something the Celluloid developers will need to fix.
