Crash in gpu::gles2::TextureManager::~TextureManager()

I’m seeing an oxide crash when running webapp-container autopilot tests on a phone (oxide 1.3.5-0ubuntu1 on vivid).
Here’s the backtrace:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

The check that causes the abort is the following:

    CHECK_EQ(texture_count_, 0u);

(when that happens, texture_count_ equals 1).
