When viewing Programmers site in Opera 11.10, I get an error message box from Opera with the following text:

No registered application for this type of extension.

I tried to track down what causes it but I haven't found any clue. I run it on Windows 7 x64, I have the following plugins:

  • Shockwave Flash - 10,2,153,1
  • QuickTime Plug-in 7.6.9 - 7.6.9 (1680.9)
  • Adobe Acrobat - 9.4.3.231
  • 2007 Microsoft Office system - 12.0.4518.1014
  • Silverlight Plug-In - 4.0.60129.0
  • Windows Live Photo Gallery - 15.4.3508.1109
  • Media Go Detector - 1.7.0.1

Update: I finally found out what causes it. Pages at Programmers try to load house-webfont.ttf, the URL is http://sstatic.net/programmersmeta/img/house-webfont.ttf. Server response has

Content-Type: application/octet-stream

It looks like Opera does not know how to handle it.

On another computer with Windows 7 and Opera 11.10 where this message does not appear, I see it requests house-webfont.woff which has Content-Type set to application/x-woff.

Disabling all the plugins did not make a difference.

Update 2: I have resolved this problem. It was connected with left-over setting of previous installs where I had ReGet installed and ReGet configured Opera to intercept downloads. The behavior of Opera changed over time… which now caused this error to be displayed.

I changed Download setting in Opera so that it displays Download dialog for application/octet-stream type. And custom fonts returned to Programmers pages.

I can't reproduce this -- the site loads fine for me in Opera 11.01 with no errors.

But I have no special extensions installed, it is a default Opera install.

    I updated the description with my findings. It is caused by house-webfont.ttf; where it works, it loads house-webfont.woff. – Alexey Ivanov Apr 23 '11 at 8:17
