Bug 462159

STEPS TO REPRODUCE
1. open ocular on a multitouch device.
2. swipe with three fingers (for example to switch virtual desktop, to bring up overview... or because you are using a pen and your palm is recognized as three fingers.)

OBSERVED RESULT
If a pdf is displayed: Okular turns gray (Not responding) but window doesn't close right away.
If in the default starting page: Okular window closes immediately

Terminal output:
```
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = okular path = /usr/bin pid = 24393
KCrash: Arguments: /usr/bin/okular 
KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi
kf5idletime_kwayland: This plugin does not support polling idle time
fish: Job 1, 'okular' has stopped
```

EXPECTED RESULT
Okular probably should not even get the three finger swipe gesture, since it should be handled by kwin or whatever does the virtual desktop switching.

ADDITIONAL INFORMATION
I'm not using standard Kubuntu but backports-extra ppa and wayland.
I wasn't able to install debug symbols because: (english in parentheses)
```
Die folgenden Pakete haben unerfüllte Abhängigkeiten: (The following packages could not be installed)
 okular-dbgsym : Hängt ab von (depends on): okular (= 4:21.12.3-0ubuntu1) aber (but) 4:22.04.3-0ubuntu1~ubuntu22.04~ppa2 soll installiert werden (should get installed)
```
Possibly because I'm using okular from backports-extra ppa. So how do I install it? I followed these instructions: https://wiki.ubuntu.com/Debug%20Symbol%20Packages Maybe the debug symbols should be in the backports-extra repo too.
