Krita logfile and the buggy file

SUMMARY
While I have Krita to graph an important work using the vector function, I found it just corrupt all my data in vector layer after i save it. After a suddenly crash it corrupted all my data. Then I create another one with autosaving to 1 min once. After i finish my work, save the file with no error information, close it to edit a new file, and then when i reopen it all the content in the vector layer disappear. Even with a third time I re graph all item in vector layer, saved once again with no error reported. When i reopen it is empty with all ojects missing once again. Now I'm completely disappointed with Krita.


STEPS TO REPRODUCE
1. create an vector layer with some chinese text object and graphs and lines and so on.
2. draw some symbol with your pen(opening a new layer)
3. save the file, close krita, reopen the file

OBSERVED RESULT
all content in vector layer is missing in Krita.
the thumbnail in explorer shows that the file is all fine, the vector content exists.
