Does archlinux install debug symbols by default? Or do you need to install
ufraw-debug or ufraw-dbg package for that? If need be, please do so... then
try:

 gdb ufraw /path/to/file.dng
r
(do whatever it takes to make it crash)
bt

and post the backtrace back here.

PS: As a sidenote, what is the source of the DNG file you're trying to
load? Is it straight from a DNG capable camera? Is it a DNG converted from
a RAW using Adobe's DNG Converter? Or is a DNG converter from a RAW using
an atrocious third party DNG converter? And what camera in particular is
the source of the original file?
