The issue was caused by usage of non-initialized image user, which could have different settings, causing some random image being loaded or not loaded at all. This caused non-deterministic behavior of Cycles image loading because it was querying image information from several places. This fixes crash reported in T50616, but it's not a complete fix because preview rendering in material is wrong (same wrong as in 2.78a release).
