#415 ufraw-batch memory error after first picture

[NicoHansi]

Using Nikon D40x
When using ufraw-batch on multiple files (ufraw-batch --out-type=jpeg *.NEF) a memory error occurs after the first picture is (sucessfully) converted.
Here is the dump:
systemd-coredump[3898]: Process 3886 (ufraw-batch) of user 1002 dumped core.

Error still occurs with --lensfun=none option.
System is Linux 4.10.3-1-ARCH on x86_64.

I have the same issue, developing DNG files. The segmantation fault happens even if you develope one file, not a serise. Using 4.10.13-1-ARCH, x86_64 too.
