I need to investigate it, but I tried to support similar behaviour for 
internal file-handling functions. I'll need to think it again. Please 
fill a ticket so this doesn't get lost when reviewing pending issues.

Yes, that's the idea.

This seems a bug, please fill another ticket with your example.
