or 
1) Right click contact and select "Other Actions" and click "Send File"
2) Select any file.
3) Immediately an error is shown titlebar says Error - kopete with text of the username of the contact you tried to send the file to.
4) File transfer fails every time.

# Expected Behaviour
1) open contact and click "Send File"
or 
1) Right click contact and select "Other Actions" and click "Send File"

I'm very surprised that kopete can't do file transfers over an open protocol like jabber, its very frustrating and disappointing.

Please let me know how I can submit more useful info so we can try resolve this bug.

I'd say its extremely important bug to fix.
