Review request for Plasma.


Changes
-------

Submitted with commit a8e54e15e13653290ca4a49a38fae742e3825d04 by David Rosca to branch master.


Bugs: 359539
    http://bugs.kde.org/show_bug.cgi?id=359539


Repository: plasma-framework


Description
-------

svgElementsCache may be created on render thread and deleted on main thread, which will make KSharedConfig crash (it uses per-thread storage).


Diffs
-----

  src/plasma/private/theme_p.cpp 2faced8 

Diff: https://git.reviewboard.kde.org/r/127112/diff/


Testing
-------

I couldn't reproduce the crash, even with QSG_RENDER_LOOP=threaded (on Intel GPU).

I think we can't just call reparseConfiguration in discardCache, because there will be race condititon (reparseConfiguration running on main thread and config being accessed from render thread).


Thanks,

David Rosca
