Hello Antoine,

Thank you for the fix. I updated to xpra-0.14.13-2.el5_11, ran "xpra
start :1001", and xpra started successfully. However, when I try to
attach to or stop the xpra instance, I'm getting the following errors:

utku at vm5:[~]$ xpra attach :1001
xpra main error:

utku at vm5:[~]$ xpra stop :1001
xpra main error:

The stop command doesn't have any effect and xpra still keeps running:
