I wonder if this is out-of-order IPC like
bug 238391
.

This wouldn't be due to out-of-order IPC. This is an ASSERT that happens when there's an installed font the web process is using, and it sends a descriptor of the font to the GPU process to use, but the GPU process can't find/access it.

Maybe the next step is to WTFLogAlways the descriptor, just in debug builds
