Crash Report generated by DrKonqi described as "Useful"

SUMMARY
Discover crashes after some time most of the time since installation of the system. From what the user has observed, the same instance Discover doesn't crash is also when it can successfully load and show the contents of the update tab.

STEPS TO REPRODUCE
1. Open Discover
2. Wait for sometime

OBSERVED RESULT
Application Crashes

EXPECTED RESULT
Application should continue to run

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 40 KDE Plasma
KDE Plasma Version: 6.1.4
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
Since installing Fedora 40 KDE Plasma Spin (around a week ago), Discover has almost always been crashing. Regardless of how it is opened, either from start up, manually on the panel, or through the terminal, Discover will open and after some time, will crash by itself - even when I closed the application before it does.

There are few instances when Discover will not crash. The most certain way seems to be to explore and search around, but this absolutely no guarantee and rarely keeps Discover from crashing. However, what always comes hand in hand with Discover not crashing, is that the Updates tab will successfully load and show its contents if any.

Any output when you run discover from a terminal and wait for it to crash?

Interesting. All your knewstuff backends are failing to initialize.

It would be amazing if you could get the output of the following commands so we can see what's happening on the http layer.

curl -v https://autoconfig.kde.org/ocs/providers.xml
curl -v https://api.kde-look.org/ocs/v1/content/data/1367056

and finally run discover with this command to get some more output on the issue

Here are the outputs of the last command. I couldn't post the first and second command output as I keep getting blocked on posting.

Hello. I've sent the outputs of the curl commands to your email.

Comment 8 Harald Sitter 2024-08-23 09:47:09 UTC

Thank you. You appear to have a bad network route to one of our servers. Maybe `traceroute autoconfig.kde.org` will help you debug what's going on.

Obviously discover shouldn't crash though.

Steps to reproduce:

- 127.0.0.1 autoconfig.kde.org in /etc/hosts
- tc qdisc add dev lo root netem delay 300s
- start discover and wait about 60s
- crash when KNS backends get marked invalid

Hello.

I've added "127.0.01 autoconfig.kde.org" to the file "/etc/hosts", and proceeded with the next command. After downloading "iproute-tc" to run the command, it returns an error: "-Illegal 300000000 time (too large) -Illegal "latency".

Ah sorry. I take it there's nothing needed from me for the time being?

I see. Thank you also for looking into this. I will keep myself updated here in case more data from me is needed. I hope we can find a resolution for this eventually. Cheers!

Comment 19 Aidan 2025-04-05 03:24:58 UTC

Hello everyone!
I have an update regarding this bug. I went to somewhere last week and noticed Discover never at all crashed during my time there, and was able to consistently update my apps and system from Discover because of that. I have gotten back home now and Discover can crash now again. It does appear the network I'm connected to really matters for this. Unfortunately I don't really have any kinds of details saved that could help compare what is different with that network to my current home one that allowed Discover to remain stable though.

Comment 20 Nate Graham 2025-04-08 17:40:33 UTC

Thanks, that seems like potentially useful information. What version of Discover are you using where you see that behavior?

Comment 21 Aidan 2025-04-09 02:22:08 UTC

I didn't think to get this detail, my apologies. But at least right now, I have Discover 6.3.4, and it was only last week I went away, so if not that, it shouldn't be too fat from it either.

I'd also like to add an additional observation. This is not related to Discover, but it seems like this change of network has also affected another application, though not a KDE App. It's Vesktop, a 3rd party discord client. Vesktop usually hangs on loading the app, and I have to restart it until it opens properly. This also didn't happen at all when I was away last week when connected to that other network. This probably means this isn't just a Discover thing, and could be something underlying in my system, or perhaps both Discover and this app just happens to handle network stuff in the same way that causes issues here in my main network. It is definitely very odd.

It would appear m_filters is null, so when we access it, the app crashes.

Looks like we don't initialize it to anything in ResourceProxyModel, which means we're counting on it being assigned a value later. Evidently in this codepath, that never happens.

I'm pretty sure that this issue gets addressed by 4af14a328701f635ad86a8fbd9ca678c9c9a6110. This will be part of 6.4, it's quite invasive and I'm not sure it makes sense to backport, although I guess it's a matter of seeing which pain is worse.

If someone can reproduce the issue on 6.3, I guess we can put together.
WRT the category not being initialised, it is (was).
