Description julianalcorn333 2021-09-26 08:37:18 UTC 
SUMMARY
Opening a archive file with Kickoff will hang plasmashell, and flood the systemd journal for about a minute before opening the file with the default application.

STEPS TO REPRODUCE
1. Create a large (about 1G) archive file (tested with zip and tar.gz)
2. Search for the file in Kickoff
3. Click the file or press enter while it is highlighted

OBSERVED RESULT
Plasmashell freezes for a while with high cpu and ram usage, and the journal also sees high cpu usage. Eventually, plasmashell unfreezes, and the file opens in the archive manager.

EXPECTED RESULT
The file opens in the archive manager as if clicked on in the file explorer

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux 5.14.7-arch1-1
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
The first time I encountered the bug, plasmashell crashed, though I could not reproduce this.

The journal is flooded with thousands of lines like the ones below.

Comment 1 Bharadwaj Raju 2021-09-26 09:09:05 UTC 
Can confirm.

Interestingly, doing the same thing from KRunner works fine, no hang.

From the logs it looks like Plasma is trying to interpret the zip file as a config file (???)
Comment 2 Tony 2021-12-21 05:28:49 UTC 
Can confirm. 
The freeze happens with all KDE launchers while opening compresed files, it varies a bit depending on the launcher. With one rar files do freeze with another it does not, also any file ~50MB will do it, with smaller files you may not notice it.

You get a bunch of these entries in the journal when it happens.

kf.config.core: "KConfigIni: ......" "Invalid escape sequence
kf.config.core: "KConfigIni: ......"" Invalid entry

applets/kicker: Skip creating KService for non-desktop files or folders

When creating a new KService, it will try to read the file as a desktop
file, but if the file is a large non-desktop file, it will hang for a
long time.

Verify the file is a desktop file, and if not, skip creating KService
and run the match directly.
FIXED-IN: 5.24.4
