Re: Problem with icns file

[Fred Kiefer]

Just to understand the issue a bit better. Are you using libicns to read the 
icns file or is the fallback to the GNUstep implementation used? The later 
implementation is rather limited and won’t be able to handle your added formats.

And why didn’t you add a 48x48 version?

Cheers,
Fred
