Hm, not this time, but i managed to reproduce the
problem (after only 1 try) with GnuCash launched from the terminal.

Here is the output with a successful save :

Transactions: Total: 734, Loaded: 740
Accounts: Total: 228, Loaded: 233
Books: Total: 0, Loaded: 0
Commodities: Total: 0, Loaded: 0
Scheduled Tansactions: Total: 6, Loaded: 5
Transactions: Total: 734, Loaded: 740
Accounts: Total: 228, Loaded: 233
Books: Total: 0, Loaded: 0
Commodities: Total: 0, Loaded: 0
Scheduled Tansactions: Total: 6, Loaded: 6
Warning: gnc_file_be_write_to_file: unable to chown filename
/home/sebmil/Mes Documents/GnuCash: Opération non permise

The chown error is normal, because a Samba mount can't change owner.
The saved file has a size of 102937 bytes.
Now, here is the output with a defective save (i just created a new
account and saved the file) :

Transactions: Total: 734, Loaded: 740
Accounts: Total: 229, Loaded: 234
Books: Total: 0, Loaded: 0
Commodities: Total: 0, Loaded: 0
Scheduled Tansactions: Total: 6, Loaded: 5
Transactions: Total: 734, Loaded: 740
Accounts: Total: 229, Loaded: 234
Books: Total: 0, Loaded: 0
Commodities: Total: 0, Loaded: 0
Scheduled Tansactions: Total: 6, Loaded: 6
Warning: gnc_file_be_write_to_file: unable to chown filename
/home/sebmil/Mes Documents/GnuCash: Opération non permise

No difference other than one more account.
The saved file has a size of 81920 bytes.

Just after, i click the "save" button one more time, and this time the
save is successful, with a file of 102982 bytes and this output :

Transactions: Total: 734, Loaded: 740
Accounts: Total: 229, Loaded: 234
Books: Total: 0, Loaded: 0
Commodities: Total: 0, Loaded: 0
Scheduled Tansactions: Total: 6, Loaded: 5
Transactions: Total: 734, Loaded: 740
Accounts: Total: 229, Loaded: 234
Books: Total: 0, Loaded: 0
Commodities: Total: 0, Loaded: 0
Scheduled Tansactions: Total: 6, Loaded: 6
Warning: gnc_file_be_write_to_file: unable to chown filename
/home/sebmil/Mes Documents/GnuCash: Opération non permise

Exactly the same as above.

After 16 tries, i wasn't able to reproduce the problem on a local ext2
partition. Maybe it has something to do with the chown error, like
aborting the save too early when the error occurs (race condition ?).

It may linked to new account creation, since i can easily
trigger the bug by this mean, but not always. One time i just
reconciled an account and saved a corrupted file. Other times i just
loaded good backup and tried "save as" on my main file, which would also
randomly produce corrupted save.

I will keep using GnuCash launched from the terminal and with the main
file on a local ext2 partition, to see if the problem triggers in the
future.

Hope this helps.
