Problems configuring a new dataset with 1.2.10

[..hidden..]

Hi List,

Have just tried installing version 1,2,10 (new install, not upgrade),  
and have run into a problem.

Following the INSTALLATION instructions, I get to the point where I  
connect to the application admin page and create a new dataset.  I  
enter the ledgersmb user and password, and the db superuser and  
password in the appropriate boxes, then go on to select the chart of  
accounts.  I enter the dataset name, and check UK_General, then click  
'continue'.

Then it all goes wrong.  After a few seconds, I'm asked if I wish to  
open the file 'ledgersmb/admin.pl', to which I answer no, and am then  
returned to the chart of accounts page.  Clicking on 'continue' again  
throws up a 'session expired' error.

In the apache error log, I see the following:
[Tue Dec 11 19:22:36 2007] [error] [client 10.42.108.1] malformed  
header from script. Bad header=Try "psql --help" for more inf:  
admin.pl, referer: https://www.ev6.net/ledgersmb/admin.pl

I have duplicated the process exactly, using a 1.2.7 installation, and  
have no such problems, so something appears to have broken between  
then and 1.2.10.

Any thoughts?
Richard
