Public bug reported:

At least on some platforms the file:list($dir) function also returns the
"." entry (current directory).

Other functions in the file module like file:copy and file:delete call file:list to retrieve directory contents but do not handle the 
current directory entry "." or parent directory entry "..". This results in an endless recursion terminating with a stack overflow.

Either all functions in the file module must handle "." and ".."
correctly or file:list simply should not return it.

This happens on the demo appserver but not on my local computer so maybe it happens only with a certain library version -
but "." and ".." entries can be filtered out using XQuery.
