Symbol’s function definition is void: ht\?

[stig]

I get this error every time I create a PR. The PR is actually created, but the buffer with my PR description is not closed, and the PR is not opened on GitHub (which I have it set to do automatically).

Here's what I see in *Messages*:

I've discovered that this problem disappears if I load marshal-0.8.2 from melpa stable instead of using the latest version.

I am also getting this error. Has there been any fixes at all other than installing an older version of the marshal pkg?
