Cannot export version 1.3.19 (456)

After updating to version 1.3.19 (456) I cannot export. Got info box:

Export Result

Sometimes normal growl-like notification shows up but ofts are not generated.
Newly created documents are exported successfully.

can you try the latest version (1.3.19 (461))

It is ok.

I just uploaded a new beta version that should fix this issue.
