Confirmed in amd64 Intrepid. It appears to be triggered by the use of TeX formatting in the label (in this case, ^=superscript): plain text labels work normally, while TeX labels appear correctly on-screen but cause this error and are missing from the output png file.
The Nabble page linked above is a report of this bug to upstream Octave, but it was sent to a development discussion list rather than to their actual bug report list, and Launchpad won't let me link it as an upstream bug watch. ** Changed in: octave3.0 (Ubuntu) Status: New => Confirmed -- Octave 3.0 print error with png https://bugs.launchpad.net/bugs/242174 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
