    Description

      Regression testing against staging/1.3.0 using the Docker image, I am seeing an immediate disconnect due to a double-free when attempting to connect to Windows RDP:

      ...
guacd[24698]: INFO:	Loading keymap "base"
guacd[24698]: INFO:	Loading keymap "en-us-qwerty"
guacd[24698]: INFO:	Connected to RDPDR 1.13 as client 0x0005
free(): double free detected in tcache 2
guacd[6]: INFO:	Connection "$e6955582-c6f2-4912-a4bd-a3ffee002cd1" removed.

      With there being a few memory-related RDP changes in the upcoming release (and with no such issues in 1.2.0), I suspect this is a regression.
