"strace -f ..." will fail, because /usr/bin/fusermount needs to be
suid root and tracing it will make it execute without the setuid.

One workaround is to run as root (if that's not desirable, you can use
the -u option of strace).  Another is to attach strace after it has
already mounted the filesystem with "strace -p PID ..."

Thanks,
