issue with open with vi

Not sure if it is just me, but when I try to open a file currently open in QC in vi
(Tools > External > Edit with vi)
I get a message on the general messages pane:

866:909: execution error: Terminal got an error: AppleEvent handler failed. (-10000)
"/usr/bin/osascript" finished with error 

After reproducing this a couple of times and switching to Terminal to try to reproduce this I noticed that this seems to have been worked despite the error message.

The respective file had been opened in Terminal, but I did not notice as nothing from the terminal gave any hint (no flashing, no activation, no bringing the terminal on top..)

This seems to be the same for QC14 on my machine.
