Comment 2 Dawit Alemayehu 2011-12-08 19:26:24 UTC
This is caused by an upstream issue. Opened a ticket and provided a patch against QtWebKit there. See https://bugs.webkit.org/show_bug.cgi?id=74108.

Bug is not upstream even though the backtrace seems to indicate that way.

Committed on 17/01/2012 at 21:12.
Pushed by adawit into branch 'KDE/4.8'.

Avoid using a nested event loops for synchronous XMLHttpRequest by letting
Qt's networking code, which can block without a need for a local event loop,
deal with such requests.

Git commit 2cf247f4ebdee44d0620e57f9cd17fa963b36b73 by Dawit Alemayehu.
Committed on 11/05/2012 at 19:35.
Pushed by adawit into branch 'KDE/4.8'.

Revert commit 462a06ea as it causes many regressions. Use KIO::synchronousRun
to fulfill synchrounous XmlHttpRequest instead.

Unofrtunately this means that the fix for the crash reported in bug# 287778
is reverted until we can find a solution for the side effects of using nested
event loops.

@Rolf unfortunately the example site provided was changed and I can no longer reproduce the crash. Do you still want this bug to be kept open ?
Comment 8 Rolf Eike Beer 2012-06-08 17:42:07 UTC
I don't think it is of much value currently. I think the bug is still there, but we know we can't reproduce it for the moment.
