Uncaught error: This socket is closed

[syntaxaire]

Same as in #12, that one was closed with a request to open a new issue if it happened again.

Steps to reproduce:

1. Running debugger on project Frescobaldi (https://github.com/wbsoft/frescobaldi)
2. Viewing file textedit.py in frescobaldi_app subdirectory, set a breakpoint on line 48, m = textedit_match(url)
3. Enter debugger command "e=../frescobaldi"
4. Press "run" button in debugger console
5. Debugger exits with code: 1
6. Press "run" button in debugger console again
7. Crash
