Emulationstation crashes with an error I can't interpret. Any ideas?

Emulationstation crashes on startup. It prints this message in the console. Any ideas of what I've done to break it?

You did nothing wrong, someone simply forgot to handle a corner case in the source code.

@fluffypillow Well, I must have triggered that corner case anyhow. I'll have to identify it, then.

To recapitulate, EmulationStation always crashes on startup when I have "ParseGamelistOnly" set to "true" with the following message:

terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string::sucbstr: _pos (which is 27) > this->size() (which is 22)
aborted

I'm using the latest EmulationStation version compiled from source to be able to use custom carousel themes. Of course I could just leave that setting set to "false" but that defeats the point of having the option.
Any ideas of what could be causing the problem?

Thanks in advance.
