When I run ps2pdf I get the following error messages:

norman@host:~$ ps2pdf test.ps test.pdf
While reading gs_dbt_e.ps:

I have tried re-installing gs and gs-esp without affect. Files test.ps, gs_dbt_e.ps and gs_cidfm.ps all checked against a working system as being good. Regardless of what postscript file I try to convert, the "Current file position is 4623" remains exactly the same. The host is running Ubuntu 7.04.

Any suggestions as to what I should re-install will be much appreciated.
