gst-inspect throws a Dbus error when DISPLAY is set

[bromeara]

Hi,
I am writing a gstreamer plugin for a usb camera and have been getting an error only when I run gst-inspect-1.0 while display is set as follows

$ export DISPLAY=:1
$ gst-inspect ./libgstpxlcamsrc.so
dbus[20467]: arguments to dbus_message_new_method_call() were incorrect, assertion "path != NULL" failed in file ../../../dbus/dbus-message.c line 1362.
This is normally a bug in some application using the D-Bus library.

  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)

$ unset DISPLAY
$ gst-inspect ./libgstpxlcamsrc.so

My version is 1.14.5 which I am locked to since I am on an Nvidia Jetson TX2 and their gstreamer plugins are build for 1.14.5 Which is also how I found out that it only breaks when DISPLAY is set since I mostly develop from an ssh terminal where it was running fine but when I tried hooking up a monitor to see the output it broke. Also, I have tried this from an SSH session with DISPLAY set manually and on the desktop with DISPLAY and all other envs auto-populated to the same effect. gst-inspect for other plugins work fine with both configurations.

Will this DBus error effect my plugin when I run it? since I'm still debugging the plugin I need to be able to figure out where the system errors begin and the plugin specific errors begin.

Also when I went to run gst-inspect-1.0 --version to get my version for this thread I got the following output.

$gst-inspect --version

I'm not really sure why my plugin would cause the version call to throw errors.
I did build this manually with cmake since I couldn't figure out how to build with meson since gst-template uses it and gst-element-maker doesn't seem to but maybe I'm missing something important in the build phase. I can post code if it would be useful but I'm not sure which parts of my plugin gst-inspect-1.0 even executes.
