Bug ID: 419852
Summary: Seg fault (double free or corruption) while detecting
faces, 0-length JPG files
Product: digikam
Version: 7.0.0
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Faces-Detection
Assignee: digikam-bugs-n...@kde.org
Reporter: jeff.w...@gmail.com
Target Milestone: ---
SUMMARY
While running digiKam 7.0.0-beta2 face detection on my large, untidy
collection, digiKam crashed on one particular file. I restarted digiKam, and
restarted face detection, and it crashed on the same file. Some notes -
probably not all relevant:
- it's crashing on a 0-length file (invalid JPEG)
- there is a space in the filename.
- there are spaces and an apostrophe in the directory name
- there are other 0-length files in the same directory which did not cause a
crash.
- the /share/ directory is a CIFS network mount, and the collection is a
"Network Share" type
Here's the directory listing:
>ls -la "/share/pics/080304 Jeff's Pics/"

Here's digiKam's appImage stdout:

STEPS TO REPRODUCE
I tried to setup a simple test album with a directory containing empty files as
above, but the issue did not reproduce. :(
OBSERVED RESULT
digiKam crashes while running face detection on odd files.
EXPECTED RESULT
digiKam should not crash due to invalid image files.
