This happens on some distributions that ship old versions of Python-Twisted (older than 10.x?) - the user will not be able to use their SSH key with Window Switch because of this.

This causes stacktraces like this one:

It will occur more often now that distros are using the AES-128 cypher when generating SSH keys.

This bug is here just as a reminder that there is absolutely nothing we can do about this: it is the distribution's responsibility to fix their buggy libraries. Once again, Ubuntu is shipping buggy versions in its "stable" release... sigh

More info ​at zenoss.org and ​their ticket

I discussed this bug on the forum (​https://winswitch.org/forum/topic/10/) and I've finally managed to get a screenshot of first bug I mentioned.

Sometimes the menu's don't expand to anything. Example: I see the local server, I click on Start Applications and the menu is empty (I just see a sliver showing something should be there, it's just not populated with anything.) However, this happens with ALL the menu options for all attached winswitch servers/connections. When this happens I can't quit the applet. However, from another system I can start applications from my that system.

See attached screenshot.

I would like to run winswitch on two current ubuntu (oneiric) boxes, both running the vinagre/vino-server VNC client/server combo. The 'Desktop Default' section in server configuration ui reads 'None available' (ui/config_server.py: populate_session_types()), and 'Start Desktop Session' is disabled.

I tried trivially adding the vinagre/vino paths to VNC_COMMAND/XVNC_COMMAND in util/commands_util.py; that did not work.

The problem persisted even after installing the tightvnc viewer.

Any hints would be appreciated.

Thanks!
