1. Start Sound Recorder
2. Click Record, wait a couple seconds, then Stop
3. Click Save-As
4. Save it as "my recording"
5. Click Record again, wait a bit, then Stop
6. Click Save-As
7. Save it as "my recording"

Result:
- "my recording.ogg" now contains your second recording
- your first recording is gone

Expect:
- It should ask if I really want to overwrite "my recording.ogg" first.

Alternatively, it could save it as "my recording #2.ogg" without prompting; this
would allow making many recordings without having to name each one as they're
made.  (The idea is to avoid causing dataloss; the mechanism is less important.)
