Comment:
Tried this with adept_updater 1.90 (Conquest, Beta1).

>From the kde panel, clicking the Adept Notifier icon to start
adept_updater. After password dialogue box, go through the update lists
phase. It then shows me the packages it wants to update. I cancel all
changes, then select mplayer-586 package, view details and when it
updates the window to show the details, it hangs.

For the hung process, a strace -p gives "futex(0x850388c, FUTEX_WAIT, 2, NULL" and nothing more.
running gdb:
