Sentry Crash Report:

Description korgens 2017-06-30 11:30:54 UTC

Application: akregator (5.5.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.7-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Just closing Akragator

- Unusual behavior I noticed:
Sometime in the last month I noticed that Akregator started to crash on initialization. Then I noticed that it had corrupted to a small size my RSS feed file. I located an older backup copy and I placed it at the correct location.

However, Akregator always corrupts that file. Sometimes the file just gets chorter and shorter. Sometimes it's unusable.

I've even tried to change the file's permissions to prevent Akregator from tempering with it, but it seems that Akregator needs to read and write the RSS feeds file all the time.

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Comment 1 Thomas H 2017-08-24 01:27:17 UTC

There are a few recent duplicates of this same bug:
https://bugs.kde.org/show_bug.cgi?id=383719
https://bugs.kde.org/show_bug.cgi?id=381929
https://bugs.kde.org/show_bug.cgi?id=378513

As one user mentioned, the frustrating part is that it attempts to save a backup to ~/.local/share/akregator/data//feeds.opml, but even that file is corrupted. All feeds are lost and replaced with the default feeds. I'm on KDE Neon user edition.
