Hi Tom, RTTI is some low-level C++ functionality to determine an objects type (roughly equivalent to `type(myobject)` in python). It can be enabled and disabled during compilation. Apparently it was disabled on your QGIS build.
The bad news: QGIS uses this information to determine which type of symbollayer is in use. The good news: This can be fixed, I've just fixed it in master [1]. Please let me know if you need this backported and where to (so you can test).
