Some images no longer working after Vaultwiki / PHP upgrade

We seem to have lost 99% of our wiki images. We recently upgraded to PHP 5.5 and the latest version of VaultWiki. If you visit http://wiki.badgerandblade.com/Image?do=list, you'll see that only a few images have thumbnails. Images with thumbnails are still working. Images without thumbnails (If you click on them) you'll notice are basically completely missing. It's almost like only part of the image data is downloaded because we get a text representation of the image rather than the image itself. It's almost like the script is terminating before sending the full data. For example, http://badgerandblade.com/vb/wiki_as...2&d=1428618493

We aren't sure what's going on here. Memory limit is what it was before. GD is available and working. VB attachments don't appear to be having any issues at all. Any ideas?

Actually, just realized that even images that are working in the wiki, their download links are outputting nonsense.

Example: http://wiki.badgerandblade.com/Image...od_stick_1_jpg

Click the download link and instead of seeing the image you'll see a bunch of garbage output.

Potentially useful information: We were also experiencing odd issues with our photo gallery software. I was finally able to track those issues down to an imagejpeg() call that was passing in an empty string as the second argument, which is no longer supported since PHP 5.4 Perhaps the vaultwiki issue is similar?

In vault/core/controller/asset/vw.php, find:

Code:

header($header, $header_value);

Replace with:

Code:

header($header . ': ' . $header_value);
