At ownCloud Inc. we have identified and fixed a severe bug in Qt's network
stack which leads to data corruption in rare cases. The corruptions are very
hard to even identify for users as the file size remains the same.

We provided two patches for both the latest Qt4 and Qt5 packages as described
in a mail to the Qt devel mailinglist:
http://lists.qt-project.org/pipermail/development/2015-May/021295.html

We would like to ask kindly to ship these patches on all supported platforms of
openSUSE to avoid users data corruption. Thanks!
