I will probably ridiculed forever for this, but here it goes:

Recently I wanted to file a bug report with Ubuntu about "document viewer" (whatever that is, I'm new to Gnome, have been using KDE, but KDE 4.x is just insane, and that's mildly put).

But then I needed to specify a package name.
Naturally, I looked for "document viewer", since that's how the window was named. Didn't find anything.

After some digging I found that "Document viewer" was actually "evince".
The logo also shows a stylized "e", so that's at least some hint.

But why not actually name the program at least **a little bit** like the binary, e.g.
"evince document viewer"
or
"document viewer (evince)"

Instead, it says in HELP/About: 

Document Viewer 2.24.1
document viewer 
Using poppler 0.8.7 (cairo)

Document viewer is a document viewer? Come on...

I'd opt either for removing the 2nd line "document viewer" OR
renaming the whole thing 

evince 2.24.1
a document viewer
Using poppler 0.8.7 (cairo)

The second line seems to be a description of what the program can be used for.

document viewer man page? Nah:

$ man document-viewer
No manual entry for document-viewer

$ man documentviewer
No manual entry for documentviewer

apt-cache, anybody? Nah:

$ apt-cache search gnome document viewer
epdfview - Lightweight pdf viewer based on poppler libs
gnome-desktop-environment - The GNOME Desktop Environment
