Bug description

I am trying to run staticfe on my single-user Pleroma instance. Since I upgraded to 5c2b6922, it returns with a blank page. However, it was still working fine on e3953923. I get errors like this in my system journal:

The offending page (and the statuses that staticfe fails to render) is at https://pleroma.marussy.com/users/kristof. I disabled the staticfe for now, so currently the default frontend is served.

I'll try to bisect this issue later. But as I am affected by #2058 (closed), building the dependencies after checking out each commit might need some manual intervention.
