I don't know if this is related, but I had problems when batch-importing pdf files from a directory. I got a result

Code:

Failed to import file1 …
Failed to import file2 …
… etc …
Failed to import file6…

Successfully imported 0 of 6 files.

I tried several times, at no avail. No messages in the system log.
Then I imported one of the files using local import, and this succeeded. From then on, batch import also worked and I couldn't get it to fail again.
