Hey Simon

MXE has lensfun of version 0.3.0.
It has a patch that is likely to fix this very issue with GLIB DLL:
https://github.com/mxe/mxe/blob/9a5b34cf036fcee967b94f30ceae120e23709e42/src/lensfun-1-fixes.patch#L173

Can you check that `make lensfun` works on your machine, please?

Few more ideas:

- update MXE's lensfun to 0.3.2
- change digikam to use lensfun from MXE
