Bug#741023: xpra attach :100 leads to 'segmentation fault'

Wenceslao González-Viñas Mon, 10 Mar 2014 04:40:31 -0700

You are right, I now do 'export DISPLAY=:0'
and after 'xpra attach :20' I get the error message in the attached file with the final 'segmentation fault' ...

The client application requires access to your local display.
You are either trying to run it from a non graphical login, or you have changed the DISPLAY environment variable.
(more than likely the latter)
