Bug ID: 409730
           Summary: "Quit" in GUI does not kill process (sometimes)
           Product: ktorrent
           Version: 5.1
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
  Target Milestone: ---

Installed: openSuse Tumbleweed 20190527, KDE Frameworks 5.58.0, Qt 5.12.3

Affected: ktorrent (5.1.1), akregator (5.11.1), krename (5.0.0) and possibly

If I close the program window (GUI) via the menu with "File -> Quit",  in some
cases, according to "top,", the associated process continues running (without

* akregator
* krename
but not systematically looked for this, <em>nor does it happen every time.</em>

the described behaviour may be considered a feature by some people. <em>I
consider unwanted network traffic a risk.</em> (Quote: “About a year ago, a
dedicated programmer published a library that lets applications just get rid of
their skin”) 
I also do have reasons to definetly wanting to end a program to free memory and
limit load on MY machine! Specially torrenting with a laptop in somebody else's
network is an absolute no-no. akregator's requests also may leak

REPRODUCE (using KDE on Linux):
* run "top" in one console
* restart "plasmashell" (killall plasmashell && plasmashell) in another
console: this will show for example continuing UTP tracker requests
(if ktorrents quits properly the message "Saving list of peers to
/home/SOMWHERE/tor6/peer_list" is shown)
* Quit kTorrent/akregator/krename by using the menu File --> Quit and watch the
