Public bug reported:

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
    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
$ unzip test
   creating: test/
 extracting: test/f1.txt             
 extracting: test/f2.txt             
 extracting: test/f3.txt             
$ 7z x

Everything is Ok

Expected behavior: Download the attached file “”, 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).
