Package: libdng1
Version: 0.2.1-1
Severity: normal
X-Debbugs-Cc: andrej.skvort...@gmail.com
Dear Maintainer,
I've worked on Megapixels, that uses libdng. The application worked
correctly until libtiff6 was upgraded from 4.5.1+git230720-5 to
4.7.0-3. After upgrade Megapixels crashes, when photo is taken with
following backtrace:
```
Thread 8 "megapixels-pr" received signal SIGSEGV, Segmentation fault.

libdng1 in archive was built against libtiff6 4.5.1. libtiff6 was
upgraded to 4.7.0 after libdng1 upload. After I've built libdng1 against
newer libtiff6 (4.7.0) crash disappeared and megapixels works as
expected.
It looks like libdng1 needs rebuilt and reupload.
