Description of problem:
krunner_lock (from kdebase-workspace-4.1.3-6.fc10.i386) still does not work when having thinkfinger input enabled in pam. If thinkfinger is enabled, it is not possible to unlock screen by fingerprint AND by password. There is a crash of kcheckpass (see backtrace below). One has always to switch to a tty and kill the process. This bug was already posted in fedora8 (394181, gets closed soon due to old version), so it seems to be the same codebase in krunner_lock as in it's predecessor kdesktop_lock. This should be given upstream to the kde dev's I suppose?

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Install and enable thinkfinger on a Thinkpad notebook and wait for KDE screensaver (with password protection).
2. Move a finger ;-)
3. Switch to the console to kill krunner_lock in order to continue working
  
Actual results:


Expected results:
At least be able to unlock with password, or even better to be able to use both password or fingerprint.

Additional info:
Here is the .xsession-errors output showing the crash:
