Unable to start dedicated server on Linux

I’m having an issue starting a dedicated server under Linux. I’m using the editor with the options: “-server -log -map Example_Map”. However, the game crashes shortly after launch with a shader error. Here is the portion of the log where things go bad:

Shader type was loaded after engine init, use ELoadingPhase::PostConfigInit on your module to cause it to load earlier.

I’m able to run the Editor and the Client just fine. The server is a no-go.

For the record, this is what was found while discussing this on IRC: SlateRHIRenderer module being loaded as part of FProjectManager::LoadModulesForProject phase (that is, too late). Why exactly this happens is unclear - the module is indeed a dependency of one of project’s modules, but it doesn’t seem to be loaded on Windows (not at that stage at least).
