Following your detailed description I'd expect it to work. The only idea I can offer at the moment (and that's what I'd try) is to run vim under strace to watch it trying to open the mailcap and perhaps to exec evince. Since mutt takes posession of the screen, it seems best to direct strace's output to a file and examine it later. Like so: strace -f -o my_trace_file -e trace=open,%process mutt (the -f is for "follow", to follow along forks; the -e filters the system calls traced (the traces tend to be a bit... intimidating). Just try to do as few steps as you have to (until mutt tries and fails to call evince), to keep the trace manageable. Hope that helps -- tomás
