[Bug 915626] Re: usb-creator-gtk crashed with SIGSEGV

[Barry Warsaw]

I was able to reproduce this, with a similar looking traceback.  I'll
investigate further.

However, suspiciously, after the crash, my machine became totally
unresponsive to keyboard input, ssh, etc.  I couldn't even get a top to
see what was going on.  I don't see anything suspicious in the logs.
This required a hard power cycle.  Has anybody else seen that?
