I'm not sure if it counts as a bug, but I encountered the same thing and couldn't find anything in the docs that suggested it should or shouldn't be able to return a list.

The simplest solution I came up with was join the list on the return and split it at the other end. 

use threads;

my $t = threads->create( 
    sub{ sleep 10; return join $;, 'fred', 1, 1.123 } 
);

print split $;, $t->join;

Usual caveats about choice of seperator apply. $; seems as good a choice as any for most things.
