Applied this change; afterwards several times created a new Pholio mock and added a Meme comment. I could not reproduce the problem anymore (first meme comment in a mock always rendered correctly instead of showing an exception as comment). However, I could not reliably reproduce the problem anyway.
- Create a meme without any above/below text
- Create a meme with just spaces as above/below text
- Create a meme with just above text as "asd", or "0" or a lizard
- Create a meme with just below text as "asd", or "0" or a lizard
- Create a meme with both above and below texts with "asd", "0" and a lizard and more stuff (doing all 64 combinations)
