This is normally a bug in some application using the D-Bus library.

Did anyone face this issue? I really need to get this resolved

Hi,
Probably you do not configure correct device node of the camera?

GUVCVIEW: couldn't open /home/simba/.config/guvcview2/video0 for read: No such file or directory

I get a similar error trying to use guvcview on the Xavier. I found that killing the ibus daemon before launching guvcview fixed it for me:

sudo killall ibus-daemon

It’s good to know this, thanks for the sharing!
