Qsys HAL error on Quartus II 15.0/Ubuntu

I'm trying to rebuild my Qsys design on Quartus II 15.0, running on Ubuntu 14.04.2 64-bit. It's an Arria II GX design, and when I try to build the PCIe core I get the message:

That error comes up whether I'm running Qsys from the GUI or just ip-generate from the command line. I can't think of why Qsys would need DBus for anything, but there you go. Anyone have any ideas? Putting in an SR will just get me told that Ubuntu isn't supported.
