I believe this bug is the same with #138196 in the upstream kde bugzilla, which can be found here: http://bugs.kde.org/show_bug.cgi?id=138196
As mentioned towards the end of that page, the problem might be related to superkaramba . I've stopped using SK, 3-4 days ago when I saw that bug report and I haven't had any problems ever since (while previously I couldn't go for even one day, without hitting this bug). Does anyone else have a similar experience, i.e. not having seen this bug after removing superkaramba ?
