SmartGit: “protocol https not supported or disabled in libcurl…” error

One of our Windows users recently ran into a strange error when trying to clone a GitHub repository, telling him “protocol https not
supported or disabled in libcurl…”. As it has turned out, he is using PureData which seems to cause troubles in combination with Git, according to this stackoverflow posting.

Switching from his custom Git to SmartGit’s bundled Git has solved the problem for him.
