True, that some GP objects export without a hitch. However, with some more complex characters (but not all complex characters or objects), it crashes every time. Here's a stripped-down part of a character used in a current production. This crashes every single time in our studio.gp2pdf_crash.blend

I don't understand why this happens with some objects and not others. So, this is going to be an ongoing problem when various departments ask for vector outputs and it crashes on some objects and not others on the same character, often times.

Can I test this commit with the 3.1.2 stable buildbot version, or should is it only in 3.2.0 alpha?

Antonio Vazquez commented

This fix will be in the 3.2 build of tomorrow.

Thank you, Antonio! It appears to be working fine, now. Can confirm on the master files it appeared on. This is so far true on Arch, Mint, and Ubuntu current versions.

Just a note: this is a pretty major feature that we use all the time in the studio for various reasons (most having to do directly with production). Would it not make sense to add this fix to another point release for 3.1.x stable? Just a thought.
