Subject: FSDB, Apache, FastCGI - ERROR: FSDB::Database::DirIsImmutableError

when I run a script [1] from the command line, it works. it asks for 
cgi pairs - key/value - cause it is in offline mode.

when i run it through mod_fastcgi => ruby it does not work.

a ruby script printing out the http_enviroment via FastCGI works (so 
FastCGI works).

If i run the script via browser (on 
http://localhost/ruby/db_connect.rb) I get the following error + 
backtrace:

-- ERROR: FSDB::Database::DirIsImmutableError

It seems to mean that I cannot change/write to the dir, right?

I have no clue what I should do about that. How can i make the script 
access the dir /tmp/my-data correctly? What is causing this error?

It should just print "Hello world, and hello database!\n" (and does 
that in offlinemode via "ruby db_connect.rb" + CTRL+D
