           Summary: Notifications by some applications only show a
                    question mark as icon
           Product: kde
           Version: unspecified
          Platform: Debian unstable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: denk at post.com


Created an attachment (id=53399)
 --> (http://bugs.kde.org/attachment.cgi?id=53399)
screenshot of notification with question mark as icon

Version:           unspecified (using KDE 4.4.5) 
OS:                Linux

Some applications (hplip, radiotray etc.) don't show a specific icon in the
title area of the notification. Instead only a question mark is shown. Attached
screenshot should make it more clear.

I know that applications like hplip or radiotray are not kde applications but,
how can it be achieved that such applications produce nice notifications?

Proposed solutions:
1. Change the look of notifications so there is no more icon in the title area.
2. The icon for the title area of a notification is retrieved by notification
system automatically dependend on the icon which is specified for the
application in the .desktop file.
3. Developers of applications which show a question mark in notifications have
to adapt their calls for a notification.

The third solution leads me to the question: How to do that and where to find
documentation about that? I'm not a developer of the mentioned applications
but, nevertheless I would like to get some information myself to help the
developers of that programs in finding a solution for the problem.

My proposed solutions are only ideas and should encourage discussion about
this.

Regards

denk

Reproducible: Always

Steps to Reproduce:
Start a print job over hplip or start playing a radio station in radiotray.

Actual Results:  
Occuring notifications show a question mark in upper part of notification.

Expected Results:  
Show either no icon or the icon of the alerting application in upper part of
notification.
