ufraw segfaults at end of file write

[Jeff Abrahamson]

When writing its output file, ufraw segfaults. This happens both for jpg and png (and then I stopped testing different file formats). Most of the time the file appears to be complete. Sometimes it is signaled as corrupt by a file viewer.

I'm not sure how to usefully debug further short of installing full source code, compiling with -g, etc.

Though perhaps this might help: the end of an strace, clipped after a long run of futex's.
