I have the same system (Galaxy Tab A, recently updated to Android 9) with the same problem. Specific messages with HTML content cause a crash, even if I don't select "show pictures."
The annoying part is, it's not consistent. Sometimes it crashes to the K-9 list of mail servers/accounts, and sometimes it crashes to the Android "desktop." For one message in particular, I was able to fully load it and show pictures... once. Since then, it always causes K-9 to crash, immediately upon opening the message. Another message crashed three times, but did not crash the next time I opened it. -- You received this message because you are subscribed to the Google Groups "K-9 Mail" group.
