Hello,
I'm having issues with the login dialog of KDE's screensaver and SCIM. The
dialog crashes every single time. I've compiled everything with -O3 CFLAGS and
CXXFLAGS, but have compiled scim, skim, scim-qtimm, and kdesktop with -O2.
This only happens when I enable the password-protected screen locking. Where
could the problem lie?
