Apart from the fact that:
- I cannot understand the intended meaning of the line $convert_file = 
fopen($write_file, "rb");
- I hope you trust the source of webservice calls, as you're not 
validating $file_name for the presence of .. (or other similar escape) 
sequences
- you could test the result of fopen before doing fwrite+fclose
- the function signature should read 
array(array($xmlrpcString,$xmlrpcBase64, $xmlrpcString));
- you could probably return the numbers of bytes written instead of the 
filename
it looks fine.

Sorry, but the Python error does not help that much.

You should:
- check the php error log on the server for any hint
- check memory_limit, max_execution_time and especially post_max_size 
php.ini directives
- enable debug mode on the php server object
