Using Windows 7 X64 and Sigil v5.3, I have had several crashes. Each time was while doing a "find next" in "all html". In "normal" or "regex" mode didn't seem to matter.
I was doing a find on ""Chapter " to change the chapter number from upper case to lower. Each time, after re-starting Sigil, I completed the same series of "finds" (and changes) without a problem.
Sorry I can't be of more help.
Regards - John
