Package: python-iptcdata
Version: 1.0.2+libtool01-2
Severity: important
Accessing one of the data fields provided by the iptcdata python
module for image http://fop3.kyla.fi/~tazle/PICT6104.JPG causes
segfault.
Steps to reproduce:
1. Download the image linked above.
2. Execute python /usr/share/doc/python-iptcdata/examples/show_iptc.py
PICT6104.JPG
Expected result:
show_iptc.py should print all IPTC metadata of the image
Actual result:
show_iptc.py prints only the first IPTC record, and segfaults on the second one
