Bug 286824

Version:           1.99.0 (using KDE 4.7.2) 
OS:                Linux

in some kmail2 sessions, search does return immediately without any results. after shutdown/restart of pc this may work again. This is what happens in .xsession-errors, when I type "xxxx" as search for my main inbox folder:



"select distinct ?r ?reqProp1 (bif:concat(bif:search_excerpt(bif:vector(bif:charset_recode('xxxx', '_WIDE_', 'UTF-8')), ?v2))) as ?_n_f_t_m_ex_ where { { ?r <http://akonadi-project.org/ontologies/aneo#akonadiItemId> ?reqProp1 . ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#messageSubject> ?v2 .
