Yes, the flash disk IS at fault. It gives problems even if you're using 
Xfce.

Another thing you might try is clearing /var/tmp/kdecache-<your 
username>/*; but this wont give issues unless your KDE installation is old.

You may try flash oriented FS; BTW reiserfs works the fastest on rootfs, 
and reiser4 is ~15 times faster (search performance).
