Version:            (using KDE KDE 3.5.2)
Installed from:    Ubuntu Packages

OS:                Linux

I have a Dell Axim X51v, I recieve files by OBEX with KDE OBEX push server ok.

When I send files by OBEX to Ubuntu if the file is less than 1 kb all is ok, but
if size is greater than 1 kb KDE OBEX push server for Bluetooth crash and cause the signal 6 (SIGABRT)

Backtrace:
