Created attachment 1693 [details] Debug log from GDB Windows 10 PRO / 64-bit OS Claws Mail version 3.14.1 This new version of claws-mail seems to crash for no apparent reason when opening certain emails. I have not discovered a discernible pattern yet. I have attached a copy of a debug session run under gdb. I hope it helps to find out what the problem is.
Can you share one or two such e-mails? Please send them to me privately (forward as attachment), so that I can try reproducing the crash.
