Description maxlefou 2023-06-25 08:13:11 UTC

SUMMARY
Some specific jpeg can't be open anymore with gwenview, causing it a segfault.

STEPS TO REPRODUCE
1. Open a jpeg file using gwenview

OBSERVED RESULT
On PNGs or on some specific jpeg files, everything goes normal. But for some other jpegs, gwenview abruptly crashes with the following logs:
qt.gui.icc: fromIccProfile: failed minimal tag size sanity
[1]    2780 segmentation fault (core dumped)  gwenview
Note that the picture appears correctly in program for one second before it crashes. The thumbnail also appears without any issues at all on dolphin or gwenview.

EXPECTED RESULT
The picture file should display and gwenview not crash.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kernel 6.1.35
KDE Plasma Version: 5.27.6
KDE Frameworks Version: 5.107.0
Qt Version: 5.15.10

ADDITIONAL INFORMATION
It doesn't seem to be related to files metadata. The same pictures used to work on gwenview before.

Please. Thank you.

done it. Tried with two faultily jpegs (one supposedly not having EXIF, or at least doesn't display them on dolphin, and the other with EXIF) they both thrown the same output:

Thread 1 "gwenview" received signal SIGSEGV, Segmentation fault.
Exiv2::ExifData::findKey (this=0x0, key=...) at /usr/src/debug/exiv2/exiv2-0.28.0/src/exif.cpp:457
457       return std::find_if(exifMetadata_.begin(), exifMetadata_.end(), FindExifdatumByKey(key.key()));   

Though, I noticed something.
The file "without EXIF" actually displays the picture a second before crash. 
The other with visible EXIF instantly crash with no displaying.
