Rarely, after waiting anywhere between a few seconds and several minutes, the
screenshot UI shows up.
The following shows up in systemd journal:
spectacle[3180927]: Error querying plasma version
"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."
STEPS TO REPRODUCE
1. Use Plasma for a while (not sure what the exact cause is)
2. Launch spectacle to take screenshot
