Comment 2 for bug 676452

(I used the dist-upgrade tool which appeared in the system tray)

Further, then I clicked the button for continuing in the error-window which resulted in the error window disappearing and the "Distribution upgrade" window not responding to input anymore. Top shows that the CPU is idle so it's probably a deadlock.
No further logs were appended to main.log

FAIL =(

Fortunately, I got a full mirror backup of the affected system so I can roll-back to that and help you in debugging this by trying again after you've released fixed packages or told me how to fix it manually.
