gpg fails to decrypt files encrypted to the same name as the original input

I noticed this very interesting behavior in my version of gpg (2.0.17):
1. take a simple text file and call it say test.txt, encrypt it to a
file named test.txt in the same directory so that it overwrites it. (gpg
-o test.txt -e test.txt)
2. decrypt file test.txt with gpg (gpg -d test.txt) and get gibberish.
It does not seem to happen when I have the output renamed to something
else. I know this is a highly unusual (and probably ineffective way) of
using gpg but I still thought it was interesting that it would fail. Any
thoughts on this (potential) bug? Can anyone else recreate it, or is it
actually a feature/unavoidable side-effect?
