I've taken your advice and created the ListJob instance in the main
thread, specifically in the slot KioFuseApp::listJobMainThread(). I
verified that the instance of KioFuseApp belongs to the main thread by
running:

kDebug()<<"this->thread()"<<this->thread()<<endl;

Strangely though, the ListJob instance that is created in the slot
KioFuseApp::listJobMainThread() belongs to the FUSE thread! Again, I
verified this by running:

kDebug()<<"listJob->thread()"<<listJob->thread()<<endl;

Could this be because I'm connecting from the FUSE thread to the slot
KioFuseApp::listJobMainThread() using Qt::DirectConnection? I tried
using Qt::QueuedConnection but the slot never seems to get executed.

Thank you very much for your help,
Vlad
