Dear Maintainer,

If I boot into single user mode (append 'single' to kernel command line) there
is a backtrace from plymouth and a delay before the password prompt is
presented. There is no problem with normal boot mode.

Transcribed from backtrace:

libc.so.6(+0x3fda0)
plymouthd(+0xa139a)
libply.so.5(ply_event_loop_process_pending_events+0x2a8)
libply.so.5(ply_event_loop_run+0x28)
plymouthd(main+0x9ae)
libc.so.6(+0x29d68)
libc.so.6(__libc_start_main+0x85)
plymouthd(start+0x21)

Thanks!
