GwenView gThumb and other crashes with Darktable JPGs

[DL4MW]

Describe the bug

Since the latest Ubuntu updates some KDE applications which uses libexiv2 crashes when trying to open JPGs which are exported from Darktable. It also seems that older Darktable images will not give that error, so that there must be changes too. the community reported, that older libexiv will solve the problem, but I cannot see that in general.

May be, the reason of this problem is just reported in other issues.

To Reproduce

Just open a Darktable exported JPG.
The backtrace is the following:

It seems this is a known issue w/ fix already in exiv2 0.27.5 and waiting to be back-ported to Ubuntu packages, so out of exiv2 hands.
