The way remmina handles device redirection with freerdp3, is not how freerdp supposed to be used - remmina bypasses official freerdp API and handles its internal objects directly. This never worked with freerdp3 properly, but with current freerdp it broke completely, since it now results in type mismatch and a SIGSEGV in the end. There's an upstream PR wich fixes the issue, at https://gitlab.com/Remmina/Remmina/-/merge_requests/2756 - which are not part of any official remmina release yet, but already applied to the master branch. Please fix this both for sid and for trixie too, -- we're preparing update of freerdp in trixie and it will be a problem there too. Thanks, /mjt
