NullPointerException in file transfer

I get the following exception transferring files (both versions 2.2.0 and 2.2.1):

Exception in thread “File Transfer jsi_1234249774005385678” java.lang.NullPointerException

Anybody know what’'s wrong?

More relevant detail: this happens only when sending to iChat. Does iChat not support any of the file transfer mechanisms that Smack supports? At any rate, smack shouldn’'t throw a NullPointerException.

I can see the issue. Though I would like to know what IChat is sending exactly that causes this. Could you post the packets you are receiving in the raw debugger output?

Thanks,

Alex
