Bug ID: 453165
Summary: Digikam crashes before starting faces detection
Product: digikam
Version: 7.6.0
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Metadata-Exif
Assignee: digikam-bugs-n...@kde.org
Reporter: vfr...@gmail.com
Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
STEPS TO REPRODUCE
1. Import a large library of photos. (Some raw file may be present)
2. Let digikam index all the files
3. Click on detect faces process
4. Wait for digikam to crash
5. Start digikam, go straight to detect faces
6. Digikam crashes instantly (just after clicking the button)
OBSERVED RESULT
Digikam crashes instantly
EXPECTED RESULT
Digikam should continue to process the files to search for faces
SOFTWARE/OS VERSIONS
Running this on Ubuntu 20.04 using appimage bundle.
ADDITIONAL INFORMATION.
The terminal shows this message:
```
Digikam::MetaEngine::Private::printExiv2ExceptionError: Cannot load preview
data with Exiv2: (Error # 59 : "corrupted image metadata"
terminate called after throwing an instance of 'LibRaw_exceptions'
```
I can't identify which file is causing the issue.
I've also experienced the same issue with the debug build. I'm attaching the
backtrace of the error. I hope it is fine.
