The original task is on Kubuntu.
I can reproduce it on Kubuntu with trunk.

The application is stuck here:

Could not reproduce with current trunk on Debian/testing. It works for me.

The bug is platform specific as I use 32 bit system (Debian/testing) and Benjamin 64 bit (Kubuntu).

This a symptom of the same problem that 44324 was/is addressing.
