When creating an attachment, the default choice for bugzilla should be to auto-detect the attachment type. If I recall correctly, this used to be the behavior, but now the default is "select from list". Being used to the old behavior, I attached some screenshots to a bug report only to find out that they were attached as text instead of as PNGs.
You'd better have the auto-detect *way* smarter before you do that. It's too eager to tag the attachments to either octet-stream or weird things like x-log. Makes them way harder to read in the browser. OG.
Red Hat's current Bugzilla version is 2.18. I am moving all older open bugs to this version. Any bugs against the older versions will need to be verified that they are still bugs. This will help me also to sort them better.
Red Hat Bugzilla is now using version 3.2 of the Bugzilla codebase and therefore this bug will need to be re-verified against the new release. With the updated code this bug may no longer be relevant or may have been fixed in the new code. Updating bug version to 3.2.
