Segfault with Secure Download

[Mauro Stettler]

i agree, to be able to help you i will need more debug info like a
backtrace. please do not forget to also include your config file. you
also mentioned that those segfaults suddenly started, do you know if
anything changed, in the config or wherever at this time?
