Description Heinrich Schuchardt 2016-08-29 06:09:29 UTC 
Version: 5.7.3 and 5.7.4

Dear Maintainer,

when I enter in the command line:

/usr/bin/plasma-discover &
/usr/bin/plasma-discover &

plasma-discover crashes with the following output:

QCommandLineParser: argument list cannot be empty, it should contain at least the executable name

KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = plasma-discover path = /usr/bin pid = 11045
KCrash: Arguments: /usr/bin/plasma-discover 
KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi from kdeinit
sock_file=/run/user/1000/kdeinit5__0
"Message recipient disconnected from message bus without replying"
QSocketNotifier: Invalid socket 17 and type 'Read', disabling...
QSocketNotifier: Invalid socket 40 and type 'Read', disabling...
QSocketNotifier: Invalid socket 36 and type 'Read', disabling...
QSocketNotifier: Invalid socket 41 and type 'Read', disabling...

Best regards
