The konsole applications tries to interprete all options after the -e options.

Try:
>>> konsole -e sh -c date
Unknown option 'c'.

According to the man page, all arguments passed after -e cmd should be used
from cmd only.

Tried with official konsole-16.08.2-3.1 and even the never version from
KDE:Applications (konsole-16.12.0-1.1) fails, too.

My old system with openSuse 13.1 had a working konsole, so I can't tell which
version introduced this bug...

With this behaviour, it is impossible to use konsole as program launcher in QT
creator if the program needs any arguments...
