Bug#352875: file-roller: Tries to guess format from file name

[Roland Mas]

Package: file-roller
Version: 2.12.3-1
Severity: normal

Using file-roller on an archive called foo.tar-1.bz2 only shows
foo.tar-1 as the contents, not the actual contents of the archive.  If I
try to open that foo.tar-1 directly (after bunzipping it), then
file-roller tells me that the archive type is not supported.  Just
renaming the file fixes the problem.

I suppose the bug is that file-roller trusts the file name rather than
the actual contents (or their magic numbers).
