yes, it's fine. 3.4.0 is just 3.3.0 plus few improvements and
bugfixes. No problem to use it in production.

We have few branched version developed by GSoc 2013 students. master
branch is stable.

yes it is, but it's not a multi-core problem here. It's a race
conditions with signal/slots from Qt that we use in image editor tools
interface.

In BQM, since 3.0.0, we use multi-core to process items in parallele.
In 3.3.0 i add an option to disable it (look queue settings for
details), because some people have a bad experience with it (target
files corrupted). Look this bugzilla entry :

https://bugs.kde.org/show_bug.cgi?id=318577


I never reproduce this on my computer (i process a lots of files here
everyday, including Sony RAW files)

So i would to know your feedback here.

Thanks in advance
