Crash on saving results in complete data loss (Version: 2.0.2, Linux)
On saving the document the application crashes, leaving behind an unreadably empty file. This happens rarely and since it results in complete loss of the data I was so far unable to reliably reproduce it.
In my opinion this is a major conceptual bug: Saving the document should be an atomic operation where, if the application crashes at any point, the state of the document is well defined. It is also a major issue since you irreversibly lose the whole document, which may be hours of work (depending on the time of your last backup).
I attached the resulting corrupted file in case anyone can draw any information from it.
