Bug#1118770: libplasma6: After upgrade, miniatures box disappeared

[Thomas <tnemeth@free.fr>]

Package: libplasma6
Version: 6.5.0-1
Severity: important

Hi !

This morning I did my upgrade routine on my debian-testing system
to find, after login, that the miniature box as disappeared from
my panel.

It is still present, however, in the applets list when I want to
add new applets to my panel. But when added back, the same behavior
reappear : an icon is in its place (looking like a miniature kde
desktop) and when I hover that icon, the "Unknown" tooltip message
is displayed.

Clicking on the icon displays a dialog window with the following
message : "applet loading error : the packages does not exist"
(translated back from french).

Changes in packages today regarding plasma:

```bash
$ ./apt-history -k plasma
2025-10-25 Install: libplasmaactivities7
2025-10-25 Upgrade: libplasmaactivitiesstats1
2025-10-25 Upgrade: libplasmaactivities-data

2025-10-25 Upgrade: plasma-desktoptheme
2025-10-25 Upgrade: libplasma6
2025-10-25 Upgrade: plasma-activities-bin
```

(note apt-history is a python script I made to help lookup for
packages changes apt history files).
