clicking datetime to see calendar causes screen to freeze/lock up

[John Pye]

Hi there

This bug is going to be super-difficult to find, as it seems to be quite intermittent.

When I click the indicator-datetime on my Ubuntu 16.04 panel, it freezes the whole system, everything becomes unresponsive. My indicator-multiload stops moving, and nothing responds to the mouse at all (although as I recall, the mouse pointer still moves). Waiting for 10-20 seconds, nothing changes.

I found that pressing ctrl-alt-1 followed by ctrl-alt-7 unfreezes the system, and things continue as normal.

Not sure if this could be a panel problem or specifically an indicator-datetime problem. But I'll report it here and if I manage to make it repeatable, I'll add more comments later.

This has happened to me on two different 16.04 machines -- a laptop and a new recently-installed desktop.

Cheers
JP
