Checked and looks like the 1.25 version of the extension is a broken zip file. I think this message can come up for a number of reasons. Maybe we should replace the message with something more meaningful like the zip file is broken or missing?
Ever confirmed: true

7zip didn't warn about a corrupt zip file.
Neither did BeyondCompare, which I used to diff the files on my machine. And at least BeyondCompare should have shown me a warning because it diff'ed every single file in the zip.
It does look like there's something wrong with the file. I got an error when trying to uncompress it on Mac OS X. You'll notice that several of the files throw the error, and a couple work fine, which makes me think the file was only partially extracted.

You'll also notice that the View Content tool is also failing for the same files, giving a File Not Found error.

The file can't be installed, either.

So, I think the real bug here is that the extraction process clearly failed at some point, and this wasn't detected in the upload and validation process. This should definitely be fixed, although it's relatively minor because we can detect the corrupt zip in the editor tools, through an error.

Yes, the most likely cause for failure here is corruption.  The library that is trying to open the file is Archive_Zip.
Target Milestone: 5.8 → Future
Is that going to be replaced in Zamboni?

this is giving the same error.  7Zip (via WinMerge) doesn't give any zip errors and seems to install in Firefox fine also.
New tools should fix this up.  Andy - can you double check?

If there's a problem in the uploaded zip file is corrupt, we won't unzip and the user will get an error. There will be a more detailed error in the logs.

For corrupt files inside the uploaded file, the viewer just won't expand them as was found in bug 653874.

If a user uploads a corrupt zip, the uploader will catch that, it uses the same code.

I think we should be good.
