Problems with plugin for pidgin

[ttlmax]

First of all, great project and thanks for providing this.

Unfortunately I have problems running the plugin in pidgin 2.13.0. A connection is established (the connection with openMittsu is interrupted as soon as pidgin connects) but I encounter the following issues:

• Adding a user is not possible, since the account is not shown in the drop down list for selection the threema account (on Debian 10 with Gnome)
• Adding a user crashes pidgin (on Ubunut 18.04 LTS with Gnome) but the account is available in the drop down list
• Sending an message to a new user (user name = threema id?) opens a chat window but any message sent just disappears without being echoed in the chat window
• Receiving a message does not open a chat window but gives the error message: "Unsupported TLS library used by CURL"

Maybe it is just some sort of mis-configuration, is there any kind of readme or documentation?

Best, Torsten
