I think the problem is this embedded Perl in the Linux agent for the fileinfo function.
A similar problem was here File Info not working on linux?
But my Perl knowledge is very limited. 
1.5 was the old bash function
starting with 1.6 it is the Perl function
I tested with “/lost+found/*” as pattern und it shows me something if there is a file inside the folder.
If the folder is empty then i also get no output. But this happens for all empty folders. There the Windows version is better as you get the output that the folder is empty.
