[Bug 795851] [NEW] software-center doesn't look inside packages for icons

[Peter Miller]

Public bug reported:

Binary package hint: software-center

When displaying package lists, or information about a specific package,
software-center looks in a number of directories for a suitable icon to
display for that package, e.g. the /usr/share/pixmaps and /usr/share
/app-install/icons directories.  It does not, however, look inside the
package itself at the files it will install, for icons that would be
installed into those same directories.  This means that an installed
program will get an icon displayed (if it installed the icon itself) but
an uninstalled program will not.  Additionally, when upgrading, the
*old* icon will be displayed, rather than the new replacement icon in
the package.

Also, none of the icon behaviour appears to be documented anywhere.  I
gleaned the above by reading the python source code.  Documenting the
icon behaviour would allow developers and packagers to know how to put
icons into their packages (icons they use for their projects and web
sites) in order to have them displayed correctly in GUI-based package
installer programs, such as software-center.  (I expected to find
something in the Debian Policy Manual, but it only speaks about app
menus.)
