sample image that is causing the crash

Here is jpg file that is causing the the crash. It is clear that libexiv
is throwing exception when it tries to parse date. This exception is not
catched in gwenview.

$ exiv2 -P X print  test.jpg 
Xmp.tiff.Software                            XmpText    13  digiKam-7.1.0
Xmp.tiff.DateTime                            XmpText    19  2014-09-13T14:36:40

Xmp.xmp.Rating                               XmpText     1  2
Xmp.exif.DateTimeOriginal                    XmpText    19  Uncaught exception: basic_string::at: __n (which is 19) >= this->size() (which is 19)

$ echo $?
1

So, fix is obvious. But where it should be fixed? In libexiv or
gwenview?

Ubuntu 21.10
exiv2 0.27.3
gwenview 21.08.1
