| Summary | Mesa/Gallium segfaults in pipe_resource_reference (dri2_destroy_image) on KDE Plasma screen locker |

This crash has happened to me three times now: once on Mesa 18.1.0-rc2 and twice on Mesa 18.1.0-rc3. After the second crash, I rebuilt Mesa with debugging enabled, so I now have a decently complete stack trace. The crash occurs when I return to my computer after having left it for a while. The monitor has turned off, although I don't know whether that's relevant. When I move the mouse to wake up the monitor, I see Plasma's screen locker and a momentary flash of garbage from various windows that were open on my desktop, and then the screen is repainted with the screen locker as normal. When I enter my password and unlock my session, Plasma is telling me that KWin crashed. (KWin automatically restarts.) The stack trace points deep into Mesa, so I assume this is the place to report a bug.

Previously I was using Mesa 18.0.0, and I did not experience the crash on that version. Here are some versions of other components in my system, in case it helps: * Linux kernel 4.16.8-gentoo * X.org X server 1.19.99.905 (1.2.0 RC 5) * xf86-video-amdgpu 18.0.1 * libdrm 2.4.91 * Qt 5.9.5 * Plasma 5.12.5
