** Description changed:
- After opening QuiteRSS it will run until crash happens. This happens
- intermittently within the hour usually.
+ [Impact]
+ This bug affects QuiteRSS and other Qt applications, like plasma-discover
(see https://bugs.kde.org/show_bug.cgi?id=402848) and qbittorrent (see bug
1814375). All they crash with similar stack traces.
+
+ [Test Case]
+ 1. Open QuiteRSS.
+ 2. Leave it running for several hours.
+ 3. It should not crash.
+
+ [Proposed Fix]
+ The proposed fix is a backport of the following commit from upstream 5.12
branch: https://code.qt.io/cgit/qt/qtbase.git/commit/?id=e431a3ac027915db
+
+ [Regression Potential]
+ This patch adds an additional check before re-sending the request.
Regressions chance is minimal, but the potential regressions may be that the
request is not re-sent where it was re-sent with the previous code.
+
+ [Original Description]
+ After opening QuiteRSS it will run until crash happens. This happens
intermittently within the hour usually.
