Is this a kdelibs regression?

[Albert Astals Cid]

Someone pointed me to 
http://quickgit.kde.org/?p=kate.git&a=commitdiff&h=3adf3cc5473c533f382ae8a481e452289a56bab3&hp=5addc104e5c181c25a3f16d596602d2755db2128

I have not had time to look at it but " fix plugin loading in KDE SC 4.10.0 " 
as commit message looks a bit scary, anyone has time to see if that was bad 
coding or is a real regression on the libs side?

Cheers,
  Albert
