Crash on Bouquets page

[stevebow]

Not sure if development is still active, but I have managed to find a reproducible GUI crash:

1. Open the Favourites page
2. Enable Move mode via the remote's menu button
3. Press the blue button (Favourites) to bring up the list of bouquets
4. Because Move mode is still active, click the OK button on the remote - "Favourites (TV)" item becomes hilited
5. Press Exit button on remote
6. Crash

Can anyone else reproduce this?

Serial log attached.

Yes. Just a Gui crash (U4).

No, worked fine (T2 & both V2s).

The cause of the crash is a segmentation violation signal from the C++ or C code in the enigma2 program (which is the application that turns the box into a PVR). The usual cause of a segmentation violation is a C (or C++) reference through a NULL pointer.

If you do a factory reset, does the problem go away? It's possible that one of the bouquet files involved is corrupted.

Restoring settings may fix the problem (provided the file corruption is the cause, and that the corrupted files haven't been saved to a settings backup).

If a system reset fixes the problem, but it's still there if you restore settings, you'll need to re-do the factory reset, and re-do your setup.

I can't reproduce the problem on a U4 running firmware version 20211010.

Even if the problem can be located and a fix found, there is currently no way of distributing the fixed firmware, so some sort of workaround will need to be found.

If a system reset fixes the problem, but it's still there if you restore settings, you'll need to re-do the factory reset, and re-do your setup.

After a bit of mucking about, I have found a sequence that reproduces the problem after a Factory Reset:

1. Do a Factory Reset via the System menu
2. On reboot, during setup, select "No, continue with the initial set up"
3. Next, do a local services scan e.g. Sydney in my case
4. At the next step, select "Skip network configuration"
5. Perform crash steps per my post 09/09 and confirm there is no crash, works as expected
6. Carry out another local services scan e.g. Sydney in my case
7. Perform crash steps per my post 09/09 and confirm that the GUI will now crash

I have done the above several times and the result is the same each time.

Okay, confirmed now. It's a bit simpler to reproduce than that, though, just select Terrestrial, instead (presumably a different bouquet to your current; the scan is making Last Scanned your current).

Thanks for confirming - and finding an easier way to reproduce. I can also confirm the crash after the initial Services scan after the Factory Reset, but for me hiliting (for move) the Terrestrial TV LCN (the current bouquet) did not crash but selecting/hiliting Last Scanned below it instead did. Here is the bouquet list as I see it after that initial scan:

• Terrestrial TV LCN (current and selected)
• Last Scanned (select this, click OK to hilite it for moving, then Exit, crash)
• Favourites (TV)

Fixed and submitted (fwiw), but given it took three years to find I won't worry about making it available.

Thanks! Not a show-stopping problem by any means, but nice to see a fix in any case. Wishful thinking, but perhaps a new build will happen one day.
