[Bug 856175] [NEW] Intel TBB + Qt 4.7 = SIGABRT (Linux 64 bits)

[Sergio Callegari]

Public bug reported:

On some usages of dlopen, TBB creates keys that get wrongly deleted by
QT so that when TBB attempts at deleting the key the application
crashes.

This is reported on https://bugreports.qt.nokia.com//browse/QTBUG-10861

While there the issue is described as a marginal case, I think it is
not. Most notably, it affects systems using nspluginwrapper with many
widely used plugins. For instance, the bug makes nspluginwrapper crash
when installed together with the googletalk plugin or some skypebutton
plugin.  See https://github.com/davidben/nspluginwrapper/issues/8 and
our own
https://bugs.launchpad.net/ubuntu/+source/nspluginwrapper/+bug/773020
that is getting tons of reports and tons of duplicates.


A fix is available for QT 4.8, but oniric appears to be shipping 4.7, so it is most likely affected by the bug.

Interestingly, the patch provided in
https://bugreports.qt.nokia.com//browse/QTBUG-10861 at
http://pastebin.com/webhbW7p is for qt 4.7 and can easily be applied to
the ubuntu packages.  Hence, please backport the fix from QT 4.8.
