New crash information added by DrKonqi

plasmashell (5.18.5) using Qt 5.13.2

- What I was doing when the application crashed:

Just changed System Font as a recommended "fix". Then I connected phone to KDE Connect and clicked on start menu. Icon bar at the bottom flashed and then the crash symbol came up.

Comment 3 andrea_scopelliti 2020-06-07 18:03:18 UTC
I have solved the problem of the plasmashell error at each boot, even if I still have randomly the same problem. 
Launching plasmashell from user terminal, I noticed this message:
"kf5.kpackage: No metadata file in the package, expected it at: "/usr/share/backgrounds/f32/default/""
So plasmashell is complaining about a missing metadata file.
I went to that directory and I found three files:
 - f32.xml
 - f32-static.xml
 - f32.png
The content of the first two files is identical and the png file is the image of the f32 background at my screen resolution (3840x2160)
This looked very similar to the content of f31, f30 etc directories, even if their structure is a bit more complex.
The conent of the f32.xml files is:
<background>
  <starttime>
    <year>2020</year>
    <month>04</month>
    <day>28</day>
    <hour>07</hour>
    <minute>00</minute>
    <second>00</second>
  </starttime>
<static>
<duration>10000000000.0</duration>
<file>/usr/share/backgrounds/f32/default/f32.png</file>
</static>

</background>
Compared to a similar file from, for example, the f31 directory the size information was missing. So I modified the <file> directive to add the size information, in this way:

<file>
    <size width="3840" height="2160">/usr/share/backgrounds/f32/default/f32.png</size>
</file>

and now the desktop does not more disappear after few seconds after boot.

Nevertheless Now the same problem appears randomly. This behaviour looks related to two independent events: 
 - If I am attending to a conference or remote lessons through a Browser (it happened with firefox and chrome, if I well remember)
 - when the plasma widget of KDEconnect receives multiple notifications, such as when my wife that never cleans her android notification area arrives at home.

In both cases the only way to recover is to reboot the computer.

Hope that such comments may help you in solving this really annoyng issue.
