"Place in Systray" and non KDE apps in systray

[Carlos A.F.]

The Kmenuedit option "place in systray" doesn't work. The systray icon of some 
applications like, for example, aMule, appears in the top left corner screen 
the when are minimized. 
The activation of the "Place in Systray" option causes a plasma error 
notification:
 KDEInit can't launch "ksystraycmd" 
Cannot load library /usr/lib/i386-linux-gnu/libkdeinit5_ksystraycmd: 
(/usr/lib/i386-linux-gnu/ñibkdeinit5_ksystraycmd.so: cannot open the objet: 
doesn't exist file or directory)
