Marcel,

My first investigations about QEventLoop has been a wrong way.

It sound like problem is about CM enabled on computer. This setting is used in
ThumbnailLoadThread. As instance is created in a separated thread and not main
application thread, through a ThreadWeaver::Job, it try to access on X11 API
which crash due to non re-entrance...

I see in ThumbnailLoadThread::Private::createLoadingDescription() that so
bracket play with CM. I forced displayingWidget to null in ThumbnailLoadThread
properties, but i think it's not enough to disable CM in ThumbnailLoadThread.

Perhaps it's the wrong way, and i must to move ThumbnailLoadThread instance
outside ThreadWeaver::Job ?
