SUMMARY
gwenview has worked previously but suddenly stopped working on my machine when trying to view any image. this dosent seem to be filesystem corruption or a hardware failure so my best guess is a software bug. 

.jxl opens correctly. havnt tested with other formats besides .jxl and the ones in the title

STEPS TO REPRODUCE
1. open any image format (tested with .png, .webp, and .gif), either as a command line argument or by opening it from gwen
2. observe the crash, segfault is recorded in terminal output

OBSERVED RESULT
Thread 1 "gwenview" received signal SIGSEGV, Segmentation fault.
0x00007ffff7d011a6 in Gwenview::ImageMetaInfoModel::setExiv2Image(Exiv2::Image const*) () from /lib/x86_64-linux-gnu/libgwenviewlib.so.5

EXPECTED RESULT
being able to open the image
