Comment 6 for bug 838507

This is not solved at all.

The same problem still exists, and, even worse, when trying to add the ppa again after having removed it with "apt-add-repository --remove" (the src entry still there), you get a corrupt list file in /etc/apt/sources.list.d/ with a src entry.

Yes, the line starts with src, not deb or deb-src.

Synaptic then throws an error and immediately closes.
