Libkgapi uses KIO::AcessManager for KDE Proxy integration, and Plasma
mobile uses the kaccounts module, which is loaded in kaccounts kded
module to import contacts using libkgapi.

This however crashes the kded on the mobile when relavant code path is
triggered. See backtrace attached. If I change libkgapi to use
QNetworkAccessManager, things works completely fine. Also, even if
libkgapi is using KIO::AccessManager and I use example code from
libkgapi which is "similar" to be used by kaccount module, it doesn't
crash, so I am not sure if is bug in libkgapi, kio, or kded? or even qt?
