           Summary: Desktop icons created with black background
           Product: Wine
           Version: 1.0.0
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org

Hi,

+ "WildLife Park 2" and
- "Jack Keane"
were installed the same day on MacOS with wine-1.1.34.  While WLP2's desktop
icon looks good, Jack Keane's icon is created with a black background (both
border and inside the steering wheel).  This black background bug is not new to
me.  It also affected the desktop icons of
- "Ankh" (the first from the trilogy),
- "Geheimakte Tunguska",
- "Felix abenteuerliche Reise",
- "Kleiner Eisbär, kennst Du den Weg?"
and several other titles when I installed them in Linux long ago (some prior to
Wine-1.0).  Other installs are not affected, e.g.
+ "Geheimakte 2".

You may scan ~/.loal/share/icons/ for all the icons that Wine created over time
on your HD.

Perhaps another issue, perhaps related: I thought .xpm would be created in
~/.local/share/icons/ only as a fallback when libpng is not available.  Well,
Jack Keane's icon was created in one format, WLP2's in the other one. How
comes?

The png vs. xpm issue was re-raised recently in wine-devel:
http://www.winehq.org/pipermail/wine-devel/2010-February/081560.html

BTW, ImageMagick also sets a black background when converting .ico to .png. 
OTOH, Eye of Gnome (eog) "Save as" works, so I've been using it to convert .ico
files found on CD to .png icons for .desktop/.command files (the MacOS Finder
displays only .png, KDE and Gnome display both .xpm and .png).

Bug #20924 seems related (black background for icon inside application).  Bug
#201 seems different to me: there should be no app calling a DIB function
rather than a strictly Wine-internal CreateDesktopIconFromIcoInExeStructure
invoked by the installer. Also, there's no single console log message about dib
or graphics during installation.
