When I import lot of feeds, after Kontact/aKregator crashes.

In the console log:

kontact(21720) Akregator::ExpireItemsCommand::Private::createDeleteJobs: Associated feed list was deleted, could not expire items      
kontact(21720) Akregator::ArticleDeleteJob::doStart: Feedlist object was deleted, items not deleted                                    

GLib-ERROR **: Cannot create pipe main loop wake-up: Trop de fichiers ouverts (too open files)

aborting...
*** KMail got signal 6 (Crashing)
