[Gtk-osx-users] Trouble loading images with gtk-osx ('Couldn't recognize the image file format for file')

[John Pye <john curioussymbols com>]

Hi all

I am getting closer with my porting of ASCEND to Mac OS X, just seeing a 
strange error here at the moment, I wonder if anyone else has seen this 
or has any suggestions.

When I double-click my "app" icon, I get this error in the Console error 
log:

24/09/09 4:21:47 PM [0x0-0x8f08f].edu.cmu.cheme.ascend[3877] 
(ascend:3877): libglade-WARNING **: Error loading image: Couldn't 
recognize the image file format for file 
'/Users/john/ascinst/Applications/ASCEND.app/Contents/Resources/glade/unlocked.png' 

24/09/09 4:21:47 PM [0x0-0x8f08f].edu.cmu.cheme.ascend[3877] 
(ascend:3877): libglade-WARNING **: could not convert string to type 
`GdkPixbuf' for property `pixbuf'
24/09/09 4:21:47 PM [0x0-0x8f08f].edu.cmu.cheme.ascend[3877] 
(ascend:3877): libglade-WARNING **: Error loading image: Couldn't 
recognize the image file format for file 
'/Users/john/ascinst/Applications/ASCEND.app/Contents/Resources/glade/incidence.png' 


However, if I open the app from a terminal, as follows:

john-pyes-mac-mini:~ john$ open -a ~/ascinst/Applications/ASCEND.app
john-pyes-mac-mini:~ john$ open -a Console

Then I don't get this error, and the above images all load just fine.

Is there some problem with absolute file paths in the following PyGTK code?

self.fixedimg.set_from_file(os.path.join(self.options.assets_dir,'locked.png'))

Any suggestions would be much appreciated.

Cheers
