[Kde-pim] Baloo search plugin crashes due to missing KGlobal::locale() (I guess?)

[Christian Mollekopf]

Hey,

I tried whipping up an akonadi search plugin for baloo, but it unfortunately 
crashes:

akonadiserver(10607)/kdecore (KSycoca) KSycocaPrivate::openDatabase: Trying to 
open ksycoca from "/var/tmp/kdesycoca-custom"
KGlobal::locale() must be called from the main thread before using i18n() in 
threads. KApplication takes care of this. If not using KApplication,
 call KGlobal::locale() during initialization.

It seems the plugin crashes in SearchStore::searchStores() because 
KPluginFactory tries to setupTranslations, and KGlobal::locale() has never 
been called. Since the akonadi server is not a KApplication, I'm unsure how to 
fix this. Ideas?

Cheers,
Christian
