Wrong bug number? Above commit does not look like a crash fix.

This didn't fix the crash. Can you maybe test on your side?

Works here, could it be that you have a corrupted cache?
Try moving away ~/.cache/kio_http ?

Aleix, did comment #4 help to resolve the issue?

No, I'm still seeing a crash. I took a while because I wanted to do a clean build of my Qt+KF5, still the same issue.

Here's the actual backtrace I'm getting:

As a temporary workaround for !release builds, I commented out 5 Q_ASSERT, lines 4988 and 4919 in http.cpp and lines 290, 301 and 320 in http_cache_cleaner.cpp.

no issue since then

https://phabricator.kde.org/D9399 < this fixes the issue for me

Testing

Git commit ca2364d9c2032e9e08e5c733b45efb97bd37f0ad by Aleix Pol.
Committed on 19/12/2017 at 22:44.
Pushed by apol into branch 'master'.

Fix crash, presumably since Qt 5.10?

Summary:
We are opening the stream as read only and skipRawData would complain that
it's a write-only device, and skipping needs reading:
QIODevice::skip (QBuffer): WriteOnly device
It was a weird optimization anyway, so just pass the information like the
rest of the data and it works just fine.

Test Plan:
The check on the bug report passes now, and akregator fetches
all feeds again.
