Hi!
By testing the taglib-sharp by multi-thread processing the bunch of jpgs I've encountered the unhandled KeyNotFoundException.
I've found and fixed the bug - added synchronization locks to protect ifd_offsets and ifd_loopdetect_refs from being modified from multiple thread simultaneously.
and tested the lib again.
It works correctly on my side now.
Would you like to merge this bugfix into the master?
