FATAL:texture_manager.cc(76)] Check failed: texture_count_ == 0u (1 vs. 0)

[Chris Coulson]

I'm hitting this runtime abort occasionally on shutdown:

[0703/194533:FATAL:texture_manager.cc(76)] Check failed: texture_count_ == 0u (1 vs. 0)

This one should be fixed now with http://bazaar.launchpad.net/~oxide-developers/oxide/oxide.trunk/revision/782

Reopened due to bug 1398354

So, despite us ensuring that the client-side doesn't delete its command buffer as long as we hold a TextureRef (which should keep the service-side command buffer, ContextGroup and associated TextureManager alive, thus preventing this crash), it looks like the service-side gets shut-down before the client-side has cleaned up:
