Comment 11 for bug 1768855

I compiled ufraw-batch with -g, and this is the result:

tarting program: /home/romano/tmp/src/ufraw-0.22/ufraw-batch --embedded-image --out-type=png --size=64 p1040069.rw2 --overwrite --silent --output=uffa.png

A debugging session is active.

So I tried to recompile it with

/* have the lensfun library */
/* #define HAVE_LENSFUN 1 */

(I was unable to find a configure option to disable lensfun) and now the resulting ufraw-batch is not segfaulting any more. Unfortunately, still I can't generate thumbnails for raw files... I'm stuck.
