After upgrading libc6 to 2.21-9, my lock-ups with kwin-x11 4:5.4.3-1.1 have gone, perhaps due to the fix of Debian bug #814958 in libc6. However, kwin-x11 4:5.5.4-2 locked up when starting iceweasel that restored multiple windows. At least I have a working set-up, but was wondering if kwin_x11 should have provided any more diagnostic information that could have helped track down bugs like #814958? Arthur.
Finally had a crash with a usable back-trace: https://bugs.kde.org/show_bug.cgi?id=359749 Arthur.
