Photo Example of JPEG 2000 (.jp2)

SUMMARY:
***
Gwenview immediately crashes and disappears when viewing jpeg2000 (jp2 photos). FYI: jpeg2000 was/is used in libraries around the world for archiving purposes- digitising old important and fragile historical ducuments (then they are put inside PDFs); they cannot be OCR'd due to very bad state of the documents- somewhat quite good enough condition to easily read the text, but not sufficient to be sutiable for OCR. The crash eliminates KDE from using in a professional environment as gwenview crashes upon hitting arrow/next (to view the next jp2 photo, not the pdf page, of course).

People have to revert to MS Windows. Not a good ad for KDE, when we have to say that it cannot be used in a professional environement and that the MS Windows is better suited for this purpose. Not good for libre software at all!
***

STEPS TO REPRODUCE:
1. Open folder with jpeg2000 photos;
2. Double click an image and browse your photos (using keyboard arrows/ or space if you reinstated the shortcut after its removal).
3. Always reproducible with crash

OBSERVED RESULT:
3. Immediate crash.

EXPECTED RESULT:
Gwenview does not crash when viewing jpeg2000 (jp2) photos, *so we can try to fix the very bad text in those archived photos directly (gimp and gm does wonders if you know what you are doing).

ATTACHMENT:
In order to confirm the crash I created jpeg2000 photo myself using openjpeg. Replicate the attached photo multiple times (under different names, of course) in a folder and then try to browse them in gwenview hitting arrow/next.
