Need help - icons for shapes missing

[Don <don886 noark net>]

It appears that dia is a fine program and getting better and would suit 
my requirements just fine ... but after installing, I have problems. 
I've asked on the Linux Debian-user list with no response.  I've looked 
at the dia discussion list for the past several months and do not see 
anything about my difficulty.  I would really like to start using dia!

Here's my posting to the Debian-user list:

=========

I just installed the "dia" package, dia starts up fine but immediately 
gives me a warning:

failed to load icon for file
 /usr/share/dia/shapes/Flowchart/display.png
 cause=Couldn't recognize the image file format for file 
'/usr/share/dia/shapes/Flowchart/display.png'

and also tells me there are 49 more messages.

I looked in /usr/share/dia/shapes/Flowchart/ and found a listing of the 
various shapes, including "display.png" and "display.shape".  In other 
words, both the .png and .shape files are there for all the shapes.

On the screen, the place where you'd normally see a small icon of the 
shape is a placeholder with a red X in the center. All kinds of them.

Clicking and dragging one of the placeholder X icons to the working 
screen, the shape/symbol is OK.  Just cannot see what the shape is until 
doing that.  So I assume the shape/symbol is OK, just the icon file 
(.png) cannot be found.

Using Wheezy, up to date, i386 version.

I'm not a newbie to Linux, but not a guru either.  Dia looks like a fine 
program for my needs.  Any help or hints on solving the missing icons 
would be appreciated.  Am I missing some packages or files?  I've gone 
thru the list on the Debian package page for dia and all seems OK.

[Not to confuse the issue, but I have another problem with synaptic that 
popped up a couple weeks ago.  In the file window, the "supported" 
symbols (the Debian swirl) and the little box indicating installed or 
not are missing in those two columns.  I only mention this here in case 
this problem is related to the missing icons above.  Synaptic does not 
give any error message and works fine otherwise.]

=========

...and I did get one query asking a couple questions, so here are my 
answers:

Yes, the rest of the 49 (error) messages do point to the various other 
shape files and all have .png extension.

Tried creating user "guest", then started "dia" from that user.  Exactly 
same results.

I completely uninstalled and then reinstalled "libgdk-pixbuf2.0-0", 
"libpng12-0", along with "dia", "dia-common", "dia-libs", and 
"dia-shapes".  Before reinstalling, removed /usr/share/dia and the 
".dia" configuration directory under the username I'm using.  Still no 
change in either dia or synaptic.

I cannot help but think my synaptic problem is related, so I tried 
starting synaptic from a konsole window (as root) and it displayed a lot 
of similar messages, only they were in reference to xpm files.  Here's a 
typical synaptic message:

synaptic:3454): Gtk-WARNING **: Could not load image
'synaptic_mini.xpm': Couldn't recognize the image file format for file
'/usr/share/synaptic/gtkbuilder/synaptic_mini.xpm'

I note that the two lib packages you mentioned are used by a multitude 
of applications and include some that I know are working satisfactory.

OK, something is messed up, either through my error or from upgrading 
Wheezy.  All suggestions welcome.

=========

And I posted the following link to a screen shot:

http://noark.net/dia-error/

to give everyone an idea of what I'm talking about visually.

Since posting the above information, I have reinstalled every dependent 
file listed for the dia package in Debian Wheezy (testing).

I might add that I am using KDE instead of gnome.

Please!  Any help would be greatly appreciated.
