install.py crashed with IOError in copyfileobj() - no reason given in error report

[Olaf]

Binary package hint: usb-creator

Updated:
USB boot disk creator terminates with error without any obivous reason (just reference to error log which contains no error information). The problem turned out to be an incomplete (truncated) iso file. Thus, reading the content failed when EOF is reached. But the exception is not catched properly nor is there any log output.

Tried to create USB boot disk from ubuntu 8.10 live cd for ubuntu 8.10_alternate iso image (which is located on windows partition). Also fails when persistence size is set to 0.

No reasons for error except 'Please see .usb-creator.log'. The logs content is:
