Attachment size 0 bytes - why?

[Grzegorz Mucha]

Hi,

recently (probably after upgrading horde 2.0-RC2 to 2.0 and imp 3.0-RC2 
to 3.0, but I can't be 100% sure) I've encountered a big problem. Every 
time I compose message and add an attachment everything seems to be OK - 
I can see "Added an attachment" message in top of Compose windows and 
the attachment size at the bottom of this windows is also displayed 
correctly. Unfortunately after sending this message, recipient gets mail 
and the attachment size is 0.

I've noticed also for a very short time, that between clicking "Send 
message" button and closing Compose Window, some error messages appear - 
it is impossible to read them because they disappear immediately 
together with the window.
I tried to increase log level to maximum but no additional log entries 
have appeared.

I'm using PHP 4.0.6-5mdk, PEAR 4.1.0 if it helps

TIA, Grzes
