I have a little python 3 test program test1.py

```
import os
print(os.getcwd())
```

Run the program with "Execute Launch" (Python 3, Working Directory: empty) then the output is

```
/home/user1/dev/kdevelop-bugs
```

Now "Debug Launch":

```
/home/user1/
```

This means when the Working Directory is not configured "Execute Launch" uses the directory of the current python file (which is handy if relative files are to be opened) whereas "Debug Launch" uses the home directory. I would expect that both Execute and Debug behave the same way.
