[Python-apps-team] Bug#741023: xpra attach :100 leads to 'segmentation fault'

Mon Mar 10 10:53:39 UTC 2014

I removed the /tm/xpra and reinstalled xpra 0.11.4 I removed all the old 
lock files of Xwindow and I killed the Xorg-for-Xpra processes. I put 
the xpra.conf with debugging.

I put 'xpra start :20' giving rise to the attached file :20.log
After setting
DISPLAY=:20 xterm

I put 'xpra attach :20' and I get the error message copied on the 
attached file errormessage.txt

If after that I put 'xpra stop :20' I get the error message: 'connection 
failed: [Errno 111] Connection refused'

Thanks in advanced !
