I doubt it; this looks like a straightforward memory bug of some kind (i.e., use after free, etc.) Could you try running e2fsck under valgrind? And could you also confirm the git commit ID of the e2fsprogs pu branch that you used to compile it? A compressed raw e2image file would be useful as well, but one problem with inline data is that a raw e2image file will have some amount of file data (for the small files that are using inline data) in the e2image file. We should probably look at teaching e2image to can zero out the contents of inline data files....
