[bug] transscripts in episode template

I get a fatal error when creating a new episode, when I have transscripts in my episode template. I’ve added this to the bottom of the template:

    <h2>Transscript</h2>
    <p>Das Transscript wird mit Hilfe eines Web-Services automatisch generiert. Wir sind uns bewust, dass wir hier nicht die beste Qualität erhalten. Unsere Erwartung ist aber, dass unser Podcast damit besser gefunden werden kann.</p>
    <p>[podlove-transcript]</p>

I’d added this after creating my last episode. When editing the episodes to configure the transscripts, everything worked fine.

With this, I get the fatal error when creating a new episode. Without it, it works fine.
AFAIK, I have the current versions installed.

Here is the error:
