[Cdash] gd-png error

[Emmanuel Christophe]

Hi,
I'm using the CDash 1.6.2 and it works well for most cases, but I have
a submission that doesn't go through and fails while uploading the
Test.xml file.

The error message on the client is just:
  Error when uploading file: .../Test.xml
  Error message was: Send failure: Broken pipe
  Problems when submitting via HTTP

On the server side, the log seems to point to a problem with some png
images included in the submission:

gd-png:  fatal libpng error: invalid distance code

This happens only with a new platform based on open solaris, our other
platforms (linux, windows, osx) don't seem to run into this.

Any suggestion on where I should start looking ?

Thanks,
Emmanuel
