xfce4-panel seg faulting when accesing guest vm turbovnc...

I'm just checking here if anyone knows if the native noVNC implementation in unRAID could be interfering with the turbovncserver I've installed separately in an Arch linux guest VM? I'm assumed it wouldn't due to it being at the Dom0 level..?

So the issue is that I'm able to login in to the desktop session via the unRAID webgui and also in to that same session directly from my chosen OSX VNC client. I use the host ip for unRAID and port 5900 in my OSX client. I can switch between web/native vnc client  and confirm that it's the same session. Everything seems to be working fine and as expected in my Arch Linux/Manajaro install. I guess this sort of VNC is kind of like logging in to the monitor port as I get to see all the startup stuff. So I guess it's not strictly the same as vnc servers that I've been used to using at the Dom1 level in the past. Correct?

So anyway once I get to the terminal in the guest I start up the turbovncserver session on port 5901 like so:

vncserver :1 -nohttpd -geometry 1440x900

As mentioned Manjaro and xfce4-panel works fine and exactly as expected using the unRAID VNC session. However xfce4-panel fails to start when I try and access the turbovncserver vnc session via the guest ip on port 5901 (i.e. vnc in the guest Dom1) - I use the same OSX vnc client (turbovncviewer) to try and access both the noVNC instigated (DOM0) and guest instigated VNC (DOM1).

So problems arise with the tubovncserver session on :5901. I can see the XFCE4 desktop load and I can right click to get to the installed apps but the taskbar at the bottom does not load and I don't get pop up windows to authenticate when trying to update my machine using the pacman gui in Manjaro. Various other windows seems to close as soon as I open them too. If I try to start xfce4-panel from with the vnc session via the terminal I see it briefly flash up and then disappear. This is the first time I've used Manjaro instead of plain Arch, so perhaps that is the problem. If anyone has any ideas feel free to let me know.

If it's not noVNC and unRAID interfering, which I'm 99% certain it is not, then perhaps it's a permissions issue, because if I start turbovncserver as root instead of as my user everything seems to work fine.Obviouslly running my VNC sessions as root is not a good solution :-)

Here's my error log from the turbovnc session started as a user from the command line:

i.e. vncserver :1 -nohttpd -geometry 1440x900

and as root

i.e. sudo vncserver :1 -nohttpd -geometry 1440x900

I know it's a bit cheeky to ask for help here when I'm almost certain my problems have nothing to do with unRAID, but if anyone can see where I'm doing something obviously dumb them please feel free to enlighten me. Thanks!
