Hi, TBH I am not too sure. I have not looked at the code. Maybe there is a fallback/default size. I think those are just GTK warnings and not the root cause of or related to the segfault/crash.
This bug I think is a duplicate of: https://bugs.launchpad.net/ubuntu/+source/putty/+bug/1720905 Maybe there you can find more information you are looking for?
