This is probably related to threading issues and timing-specific. Something
needs to be protected to avoid being accessed when it shouldn't be. Likely the
old file is in the process of being destroyed while being compared with the new
file or something like that.

Does the attached workaround prevent the crashes? It is not a proper fix we can
apply, but until we have a good solution it could help.
