System specs

Ram: 16GB
CPU: AMD Ryzen 3600

Did you install Natron using the official installer?

• Yes, I used the official installer
• No, I installed from a binary archive
• No, I compiled Natron from sources
• No, I installed Natron via another method

Custom installation path

~/Natron-2.5.0/

What were you trying to do?

I have a project with a bunch of linked properties, one of them has a singular keyframe that can't be touched or deleted else Natron crashes.

What did you expect to happen? What happened instead?

project_brokey.zip

Step-by-step reproduction instructions

1. Open the above project
2. Select the node called "progress"
3. Try to delete or move the size keyframes, particularly the height component

Additional details

• I have tried manually deleting the Keyframes from the file, to no avail
• Copying the nodes to a separate project yields the same result
• Starting Natron with --no-settings and/or --opengl disabled yields the same result
• I can't get Natron to spit out a coredump but the command line gives me the following Backtrace:

Caught segmentation fault (SIGSEGV) from thread Main(0x25b637e0), faulty address is 0xb11a5a from 0x701401b0
