Im back with some more results.

This time I tried to make compessed backup without md5 generation. During backup, there were again no crashes. During restore (set to skip md5) it crashed again (well, froze for like 20 seconds and than restarted) - last records in log were along these lines:
Formatting - something (system i guess) - to - something -
Done.
(sorry, blame my short-term memory

)
Anyway, it deffinitely wont be md5 related, as both backup and restore logs clearly stated that md5 check is disabled.
