Segfault on close

This has been present in all versions I use. Upon closing, we see this in the console: Also, the "Failed to connect to server" popup occurs.

However, functionality is not affected in any way.

This is on Ubuntu Budgie 18.10.

$ gcc --version gcc (Ubuntu 8.2.0-7ubuntu1) 8.2.0 $ qmake --version QMake version 3.1 Using Qt version 5.11.1 in /usr/lib/x86_64-linux-gnu

Yes, the current shutdown and clean-up of the MQTT library is still rather messy. The code will be refactored to prevent this issue from occurring. Please standby :)

A new release (v0.3-alpha) has been made available. As the crashes and stability issues originated in the libmosquitto library, it's expected that by swapping it with NymphMQTT such crashes and stability issues should be much reduced.

Feel free to try the new code and let me know if you need any assistance with the new dependencies (NymphMQTT and its dependencies).
