I have downloaded several different Office documents off of different websites and WebKit appends a strange filetype extension to them. For example, WebKit adds .pot to filename.ppt, .xla to filename.xls, and filename.dot to .doc. I have been able to reproduce this issue on several websites with several different Excel, PowerPoint, and Word files.
Here is a link to a post on the MacRumors forum from some other Safar/WebKit users who have been experiencing the same problem http://forums.macrumors.com/showthread.php?t=445758. It seems to occur after the installation of Office 2008, however other browsers like Mozilla Firefox, Camino, and Opera are not affected by this issue.
It does not change the extension, it adds it. So file.doc becomes file.doc.dot and file.xls becomes file.xls.xla. Flash video files file.flv becomes file.flv.dms.
In my opinion the issue belongs to Safari browser, not to Webkit engine. So it should be reported to http://bugreport.apple.com The issue is of cause visible only on Mac platform.
I have submitted a bug report on Apple's Bug Reporter. The problem ID is 5827353. (In reply to comment #3) > In my opinion the issue belongs to Safari browser, not to Webkit engine. So it > should be reported to http://bugreport.apple.com The issue is of cause visible > only on Mac platform.
Thank you for filing this bug! As it is indeed not a WebKit issue, I'm closing this Bugzilla report as INVALID; it will continue to be tracked in Radar.
