This is again using /tags/0.17.x@12466
This happens when you control-c, in various places. (see also #18 from 4 years ago!) It should not happen if you use "xpra stop" to shutdown, which is the preferred way of terminating the server process. We may try to improve this in the future, but changing the signal handling is known to break on some platforms (win32 and osx), and cause problems with GTK3.. so don't hold your breath.
Milestone renamed
Very difficult to avoid unfortunately, just use "xpra stop".
