SUMMARY

Closing Dolphin window will not terminate the process or it's relevant file.so
and trash.so. Opening a new Dolphin instance will launch a new process and
friends. With time these processes accumulate depleting resources, mainly RAM.


STEPS TO REPRODUCE
1. Open Dolphin
2. Close Dolphin
3. GOTO 1

OBSERVED RESULT
Dolphin window closes, but process does not die. Process cannot be brought to
the foreground again or used for anything.

EXPECTED RESULT
Dolphin and it's related {file|trash}.so processes die when the window is
closed.
