I have seen this sort of crash before (usually on shutdown with control-C), but this seems to happen during runtime which is more problematic... The ​original bug (was on the wrong tracker) says this happens on clicking "Apply" in the options window (I assume the main 'Configuration' dialog - not the server options?).

I first thought that this was due to pybonjour, but the backtrace also seems to point to pynotify (and gio/dbus) - maybe we need an idle_add call on the notify path?

Hi, I do not know where to post this issue sorry if this is already posted.

I recently installed winswitch on a newly installed ubuntu computer.

xpra 0.7.30, nxserver, vnc server, sshserver are all installed

I try to run the the application but nothing works. When I start an application from the applet, I have a notification is says, "server not responding", or "something went wrong".

I tried by hand to run the server, and the command parser but it does not work either.

I checked Xpra and it does work manually.

I do not know what to do or change to make it work

this is the std output from the client, which seems to be the source of the problem.

It would be nice if winswitch could be attached to a server via a shell command, similar to "xpra attach".

This is related to #168, too.

Thanks a lot.
