gwenview aborts with a std::out_of_range exception raised in libexiv2

The problem seems not to appear on x86_64!

On another system gwenview opens the very same file.

Working packages on x86_64:
libexiv2-14:amd64 0.25-3.1ubuntu0.18.04.1 amd64
gwenview 4:17.12.3-0ubuntu1 amd64

Non-working packages on x86:
libexiv2-14:i386 0.25-3.1ubuntu0.18.04.1 i386
gwenview 4:17.12.3-0ubuntu1 i386
(sorry they were truncated in the bug description)

Please try to improve the quality of the backtrace by installing the debug packages for libexiv2 (and possibly gwenview) and providing more lines of output

Here is a more detailed gdb output

terminate called after throwing an instance of 'std::out_of_range'
  what(): basic_string::at: __n (which is 19) >= this->size() (which is 19)
