    Description

      In an application which loads multiple images over the network, a crash could be observed (see backtrace).

       

      This happened after creating an Image inside a StackView (among other things), and then quickly navigating away shortly afterwards.

       

      The reason for the crash is that job->data is nullptr, and in contrast to line 890, we don't check for that before assigning to job->data->frameCount.

       

      I haven't tried to create a reproducible test case yet.
