Bug ID: 505497
Summary: Kaffeine crashes when adding multiple DVB-T channels
Classification: Applications
Product: kaffeine
Version First unspecified
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: mche...@kernel.org
Reporter: alxlve....@gmail.com
Target Milestone: ---
SUMMARY
The DVB-T channels found from a fresh DVB-T scan can not be added to the saved
channels of Kaffeine. Kaffeine immediately crashes on clicking 'OK' on the
Channels / Scan window. This bug affects the latest release of Kaffeine: 2.0.19
Whether Kaffeine's installation comes from the Arch Linux official repositories
or Flatpak (Flathub) the bug is present.
STEPS TO REPRODUCE
*For the ease of reproduction I will give instructions for the Flatpak
version.*
1. Install Kaffeine's latest Flatpak package `flatpak install org.kde.kaffeine`
2. Scan DVB-T channels, add all selected channels or all filtered channels (on
the right pane) to the saved channels list (on the left pane)
3. Click 'OK' (to save), Kaffeine immediately crashes
4. Adding a first single channel works, the channel is saved and Kaffeine does
not crash
5. Adding a single or multiple channels thereafter does not work, Kaffeine
crashes and the newly added channel(s) are not saved
OBSERVED RESULT
Kaffeine crashes and upon restart the changes haven't even been saved.
EXPECTED RESULT
Kaffeine shall not crash and the channels shall have been saved.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.1
Kernel Version: 6.12.33-1-lts (64-bit)
Graphics Platform: X11
ADDITIONAL INFORMATION
DVB-T Device: DiBcom 7000PC Hauppauge WinTV-NOVA-TD (Dual tuner with Diversity
mode)
Kaffeine did not have this issue a few months ago, i.e. last time I performed a
scan.
WORKAROUND
*For the ease of comprehension I will use the standard location of Kaffeine's
configuration files in the following steps.*
**The Kaffeine's user configuration directory used by the Flatpak package can
be found under this location: `~/.var/app/org.kde.kaffeine/data/kaffeine/`**
1. List available Kaffeine's Flatpak packages `flatpak remote-info --log
flathub org.kde.kaffeine`
```

2. Run Kaffeine and update the latest scan data, copy the
`~/.local/share/kaffeine/scanfile.dvb` file to a safe location
3. Install the previous version of Kaffeine's Flatpak package `flatpak update
--commit=264b8892e0380daaddf134c92ccba867c896d9e30ce78348ec24f43095676e30
org.kde.kaffeine`
4. Copy back the previously saved `~/.local/share/kaffeine/scanfile.dvb` file,
the update scan data function is broken on this old version
5. Scan and add DVB-T channels as usual
6. Copy the `~/.local/share/kaffeine/sqlite.db` file to a safe location
7. Purge Kaffeine's installation `flatpak uninstall org.kde.kaffeine
--delete-data`
8. Install the latest version of Kaffeine's Flatpak package `flatpak install
flathub org.kde.kaffeine`
9. Run Kaffeine and update the latest scan data (optional), quit Kaffeine
10. Copy back the previously saved `~/.local/share/kaffeine/sqlite.db` file
11. Run Kaffeine, the channels are shown in the saved channels list and can be
watched
12. Editing the details of a single channel even works
