[sane-devel] Double-free following scan on ubuntu hardy 8.04 with epjitsu fi-60f

[Jeff Kowalczyk]

My Fujitusu Fi-60f produces a color scan on Ubuntu Hardy 8.04 Desktop,
but emits a double-free error at the end.

My purpose of this post is to gather information for a proper bug report
to the attention of Ubuntu.

If anyone knows how to correct this directly (rebuild package, etc.), I'd
be very interested as well, as we're going to use this scanner immediately.

The error does not prevent me from using scanimage, but the more
user-friendly GUI scan tools, gscan2pdf in particular, encounter an
intolderable number of modal dialogs announcing the error.

Thanks,
Jeff
