ktorrent: symbol lookup error ???

["Mehmet Fatih Akbulut" <maillisteleri@gmail.com>]

hi all,
i am using debian unstable.
after last upgrade;
i get the error: 
ktorrent: symbol lookup error: /usr/lib/libktorrent-2.2.5.so: undefined symbol: fstat64
when i try to open Ktorrent.
besides i can't even start Ktorrent if i remove .kde/share/apps/ktorrent directory.
get the same error above.

i got a similar error yesterday when i tried to burn a cd with k3b.
(error was: k3b: symbol lookup error: /usr/lib/libk3b.so.3: undefined symbol: stat64)

what is wrong with debian ?
what should i do in order not to get errors above ?

thanks in advance,
bye.
