I've had this same crash twice more, but the cause is random. Git commit aa16993845558a589689055cf64e51a4b4b4931f by Dmitry Kazakov. Committed on 18/06/2018 at 12:57. Pushed by dkazakov into branch 'master'. Possibly fix the crash when dropping low quality frames from animation cache I couldn't reproduce the bug, so I'm not sure it actually fixes the bug, but dereferencing end iterator sounds like a possible reason.
