This is a bug in QtWebKit (QTBUG-41360 [2]) and has been fixed upstream
[3].
It’d be great if you applied that patch to the Debian package and get it
into Debian Jessie before its release, as this issue has been set to P2
– important upstream and as the crashes might cause non-serious data
loss, when Arora crashed while I typed in a message in a Web interface
or Wkhtmltopdf, often used by other applications, does not create the
PDF.
The work-around of installing the package `gstreamer0.10-plugins-base`
is not feasible, as the user wastes their time figuring out the cause
for the crash – a note in the release notes would be necessary – and
there is a patch available. Depending on `gstreamer0.10-plugins-base`
would be possible too, but applying the patch seems the better choice.
Thanks,
Paul
