Description of problem:
I tried to import a bunch of test images, the import started but generated quite a few errors and warnings.

At some point the import stalled ("About 15 seconds remaining" was displayed in the status bar) and after the while I was forced to quite application.
Several processes remained active and had to be killed form the command line.

After doing that the application could be started again but running the import again resulted in a similar problem.
ps indicates that the main program is now defunct:

It might be related to the fact that some of my test images are somewhat corrupt:
