I think it's better to notice user in the installer.

Hi,

p11-kit uses "_spawnv" to launch trust.exe, but I found that "_spawnv" has a bug in handling whitespace characters.

The 3rd argument of "_spawnv" seems to be passed to the command as a single string, even if it is separated by an array.
If you enclose them in double quotes, they are treated as a single argument.
However, if argv[0] is enclosed in double quotes and passed to the 2nd argument of "_spawnv", an error occurs.

Details are available at "https://github.com/vmi/mingw-spawnv-bug".
