In Nautilus XLS and MP3 file types are recognized as "comic book archive"

[Jan]

Binary package hint: nautilus

I have some usual MP3 and XLS files which are displayed in nautilus as "comic book archive". It appears in the "type" section of a file list in Nautilus. Double click on the files does it not open but Nautilus shows me instead a warning message that the file extension (XLS resp. MP3) and file content (comic book archive) differ which might be a security threat. The files are ok and open properly directly from applications. What is comic book archive?!

This is intriguing. We need more information to understand better what is causing this to happen on your system.

First, does this occur with all and every MP3 and XLS file on your system?

Second, does it occur with other files?

Third, what does the output of the 'file' command tell you when run on one of these files? For instance, if the file was named star.xls, you would run:

   file star.xls

and tell me what the output is.

Finally, what version of Ubuntu are you using?

Sorry, I am using Feisty. Right now I experienced that the two files I had this problem with are not anymore recognized as described before. Also "file" seems to think the same:

file Ac.xls: Microsoft Installer"
file The Changeling.mp3: Audio file with ID3 version 23.0 tag, MP3 encoding

So I don't know how to reproduce the strange behavior.

Ah. Well, I'm happy the problem doesn't occur for you any longer. If it does and you find a way of reproducing it, let us know. Thanks!
