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 *** While scrolling through images in Preview mode, clicking on (seemingly) random images causes a freeze ("Not responding") that lasts several seconds. Using DebugView shows that some error occurs in Exiv2: ============ [4280] digikam.metaengine: Exiv2 ( 3 ) : XMP Toolkit error 201: Error in XMLValidator [4280] [4280] digikam.metaengine: Exiv2 ( 2 ) : Failed to decode XMP metadata. [4280] [4280] digikam.metaengine: index : 0 [4280] digikam.metaengine: properties: 2 [4280] digikam.metaengine: Exiv2 ( 3 ) : XMP Toolkit error 201: Error in XMLValidator [4280] [4280] digikam.metaengine: Exiv2 ( 2 ) : Failed to decode XMP metadata. ============ However, after a few seconds digiKam responds again and displays the image just fine. Afterwards, clicking on the same image does not seem to cause similar issues. In the attachments I've added an image which caused the same behavior. As noted above, though, the issue doesn't seem to happen when clicking this image again later. STEPS TO REPRODUCE 1. Select preview mode 2. Begin scrolling through the images, clicking on different as you go (doesn't have to be in order). OBSERVED RESULT digiKam hangs on certain images, displays a "Not responding" status. Comes back after a few seconds, continues to work fine until the same behavior repeats. EXPECTED RESULT digiKam should not hang on any of the photos as they are all valid, straight-out-of-camera Fujifilm raw files. SOFTWARE/OS VERSIONS Windows: Windows 11 Home, Version 21H2, Build 22000.469 ADDITIONAL INFORMATION
The XMP-XML structure in these images is incorrect. The Adobe XMP-SDK reports an error and mostly cannot read the XMP metadata. Possibly the Adobe SDK that Exiv2 uses is too old. We already know the problem (including freezing) from other Windows users. Which Fujifilm camera are the images from exactly to reproduce the problem? Maik

Please, let me know if there's a standard way to attach large files, as it seems that the RAW file is too big to attach directly here. Also, I'd be happy to provide anything else that can be useful.
Bugzilla attachment sizes is limited. Use cloud link instead, as gdrive, dropbox, etc... Gilles Caulier

Hi, The digiKam 7.6.0 pre-release includes a rolling release of Exiv2 from github. Code is updated each day while compiling the Windows installer. https://i.imgur.com/8icqXqH.png Please try with this new version to see if problem is fixed in Exiv2. Installer is located here : https://files.kde.org/digikam/ Thanks in advance Gilles Caulier

I've replaced my instance of digiKam with today's build of 7.6.0, and confirmed that Exiv2 snapshot from today (Feb. 5 2022) is being used. The first image I opened has caused a freeze. After further investigation, it seems as though every image I open causes the same error to show up in DebugView. However, freezes only occur occasionally and I was not able to identify any difference in the logs for files that cause freezes vs. those that do not.
I can also reproduce the problem with samples from the web using the Exiv2 CLI tool. The XML seems fine: <x:xmpmeta xmlns:x="adobe:ns:meta/"> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <rdf:Description rdf:about="" xmlns:xmp="http://ns.adobe.com/xap/1.0/"> <xmp:Rating>0</xmp:Rating> </rdf:Description> </rdf:RDF> </x:xmpmeta> A test with ExifTool and active validation shows a warning in the Fujifilm RAW file: exiftool -xmp:all -validate -warning -error DSCF2022.RAF Rating : 0 Validate : 1 Warning Warning : Value for FujiIFD tag 0xf010 VignettingParams overlaps tag 0xf00f ChromaticAberrationParams I have tested all my Fujifilm sample images, which are from different cameras, all are valid. My guess is that Exiv2 doesn't find the XML block start correctly. The problem would have to be reported to Exiv2 along with the test image. Maik
