Rhythmbox desktop launcher icon appears too small

[Jeffrey Knockel]

Binary package hint: rhythmbox

After the gutsy update to Rhythmbox 0.11.1, when creating a desktop icon for Rhythmbox, the icon appears way too small. To reproduce, go to Applications -> Sound & Video -> Right click on Rhythmbox -> Add this launcher to desktop. This issue was not present prior the update to Rhythmbox 0.11.1.

Thanks for your bug report.

Well, As a workaround you can always right-click it and use the "expand the icon" feature.

Thank you for your bug. What icon theme do you use? I don't get the bug using gutsy

[Jeffrey Knockel (jeff250)]

I use tango. However, I can reproduce this from a fresh Tribe-4 live cd boot-up, so human as well. In fact, I've been playing around, and I've found some other icons that do this too. I've attached a screenshot that shows all of the icons of the default ones in the menus that have this problem for me (on the left) and a portion of the ones that don't have this issue (on the right).

Same issue here with gutsy full upgraded.

See Bug 46836 (the same for Sound Juicer).

not something that should delay gutsy

The stretch corners behave opposite when you drag them.

[libertyernie (libertyernie)]

I just realized that whether or not the icons behave correctly depends on if they are in PNG or XPM format. Firefox has a PNG icon, Rhythmbox uses an XPM icon.
Also: check out ~/.nautilus/metafiles. The one for your desktop contains XML entries for each icon; I added
icon_scale="2.56"
for the misbehaving icons. This makes it exactly 32x32, at least for Rhythmbox and Movie Player.

This seems to be the same as bug #46836.

[libertyernie (libertyernie)]

Also as #35065.

These two should be marked as duplicates of this bug.
Coming from KDE this is extremely annoying to me when I'm using GNOME.

This issue can be avoided by having the application install a png in /hicolor/48x48/apps
Will file bugs towards the apps that don't.

Wouldn't the right way be to fix nautilus to use svg icons correctly rather than to add new variants to every application to workarounding the bug?

[Andreas Nilsson (andreasn)]

Yes, probably. As I told you on irc, when I spoke to Alexander Larsson about this, he suggested we should solve it this way. I'll check with him again and investigate this a bit deeper though.

There is no need to provide 48x48 pixel png icons for each application. As described in bug #46836 Rhythmbox, Sound Juicer and other applications svg icons have an initial size of 48x48 pixels.

But /usr/share/icons/hicolor/index.theme contains the following:

[scalable/apps]
MinSize=1
Size=128
MaxSize=256
Context=Applications
Type=Scalable

So the gnome icon theme implementation thinks that icons in the scalable/apps directory have a nominal size of 128 pixels. For Rhythmbox, Sound Juicer, ... icon the actual size is 48x48 pixels, so the icon appears 2.67 times smaller than expected.

There are two possible solutions:
1. edit index.theme and set the nominal size of icons in scalable/apps to 48 pixels.
2. edit the SVG files so that they have an intial size of 128x128 pixels.

I would recommend (1) because 48x48 is used in gnome as initial display size for desktop and folder icons. Furthermore the tango project also suggests 48x48 pixel size for svgs. Most of the scalable icons in /usr/share/icons/<theme>/scalable already use this size.
