With Python2.5 as default, php5-recode package a white blank page for the file "test.psp" like this : """ <html> <body> <h1><% req.write("Hello!") %></h1> </body> </html> """ With Python2.5 as default, without php5-recode package the PSP file return *Hello!* No traces in the log of Segmentation fault in the time I've made the tests. ### [Fri Dec 05 13:26:43 2008] [notice] Apache configured -- resuming normal operations [Fri Dec 05 13:27:10 2008] [notice] caught SIGTERM, shutting down [Fri Dec 05 13:27:13 2008] [notice] mod_python: Creating 8 session mutexes based on 150 max processes and 0 max threads.
