This is hitting a release assert:
https://searchfox.org/mozilla-central/rev/11a2ae294f50049e12515b5821f5a396d951aacb/gfx/layers/client/TextureClient.cpp#1584
Looks like the message passed in a bad shmem. The best we could do is pass the error up and let the texture creation fail, but I'm not sure if that is really an improvement over the assert as it stands.

As in comment 2, I think we are doing the right thing with the assert.
