For any .zip archive generated by the ownCloud software, it seems that
extracting the files using Nautilus results in correctly-named
directories/files to be created, but all files are actually empty (0
bytes). The archive can be extracted without issues using file-roller,
unzip or 7z:
$ unzip -t test.zip
Archive: test.zip
testing: test/ OK
testing: test/f1.txt OK
testing: test/f2.txt OK
testing: test/f3.txt OK
No errors detected in compressed data of test.zip.
$ unzip test
Archive: test.zip
creating: test/
extracting: test/f1.txt
extracting: test/f2.txt
extracting: test/f3.txt
$ 7z x test.zip

Expected behavior: Download the attached file “test.zip”, right-click the file
in Nautilus and choose “Extract Here”. A directory “test” containing three
non-empty files “f1.txt”, “f2.txt” and “f3.txt” should be created.
Actual behavior: All three files are empty (0 bytes).
