Just as update, this problem occurs *ONLY* if the little flag for switching keyboard layouts is activated. No keyboard layout switcher in kicker -> no segfaults of screenlocker. Git commit 937c7245f0f4058d2b335d160617c1cdb2398cb7 by Andriy Rysin. Committed on 03/04/2011 at 04:27. Pushed by rysin into branch 'KDE/4.6'. Fix null pointer crash when no rules found; add unit test BUG: 269961 M +1 -1 kcontrol/keyboard/flags.cpp M +3 -0 kcontrol/keyboard/tests/flags_test.cpp http://commits.kde.org/kde-workspace/937c7245f0f4058d2b335d160617c1cdb2398cb7 I've pushed the fix but it looks like you don't have the rules file in /usr/share/X11/xkb/rules (there must be a warning in your .xsession-errors file), would you know why?

Hmm in the trace it says rules=0 so the rules must be missing, is you keyboard layout settings disabled? I would grep session-errors for "rules" huettel@pinacolada ~ $ grep rules .xsession-errors huettel@pinacolada ~ $ In normal operation (i.e. outside kscreenlocker), the "layout switcher" (little flag) is enabled and works as expected, i.e. I can switch between German and US-English keyboard. ah right, embedded kxkb widget does not use rules they are always 0, I guess the problem was worse than I thought, I am glad I could address it quickly, thanks for the report! Thank you for fixing it so quickly! I'll try to persuade the packagers to add it to 4.6.2. |
