- What I was doing when the application crashed:
I configured my panel with panel to be auto-hiding. Sometimes Plasma crash
while moving mouse cursor into taskbar to make it visible. I saw just shadow of
panle and then all computer do pause for some seconds. Usually at these times I
in parallel use other programs, that may do sinnificant operations in disk or
with RAM.
