Maik, now that is interesting... I've just downloaded an ISO to check your findings and at some point after navigating to the location of the ISO I see the error that you reported so I can confirm the bug although I'm not sure of how to amend the bug description so that others can reproduce the problem but I was definitely able to start usb-creator more than once earlier.
May be we only see the bug after navigating to the downloaded ISO the first time but usb-creator will always crash afterwards? ** Changed in: usb-creator (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1962862 Title: usb creator crashes on startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1962862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
