When this happens, unity8.log says:

[2016-44-29:16:44:10.737] Failed to check if source is video: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Part of the issue is that qtubuntu-media is using blocking dbus calls, it should avoid that however possible.

Status changed to 'Confirmed' because the bug affects multiple users.

Is this still an issue after the last OTA release? OTA 12 included a big media-hub deadlock fix.

[Bob Harvey (bobharvey)]

NO idea. I have packed the tablet away, it was just too buggy and too unuseful to waste any more time on.

[Jim Hodapp (jhodapp)]

bobharvey: if you wouldn't mind giving it another try I think you'll find the experience has been greatly improving with OTA-11 and OTA-12.

[Bob Harvey (bobharvey)]

Ok, unboxed tablet, upgraded to OTA12, tried again

I have made around 30 screenshots without problems.

Nowt else seems radically different so it will go back in the box later today.

[Jim Hodapp (jhodapp)]

Thanks Bob for confirming that it's fixed for you.
