1. Segfault, yes, but with careful management, it can still create a
[persistent] live USB drive. Many people would be happy, if this poor
program will get some love, and get rid of the bugs.


2. A bug-free alternative is usb-creator-kde. I have tested it and found
that it works without issues (only warning output to the terminal
window, if started from that).

I checked the size in a clean persistent live USB drive with Lubuntu
13.04 32-bit. With all the KDE packages, 384 MB more disk space will be
used, so it could be recommended for people with a [fast] internet
connection, but it cannot be included in a Lubuntu CD-size iso file.

Best regards
Nio
