Comment 1 Dominik Haumann 2014-11-14 20:11:36 UTC

@Tigran: Did you upgrade KDE and maybe not restart KDE? Or do you run kate or KDE very long (say 1-2 weeks) without rebooting?

We once had a report similar to this one in bug #315690, but since we cannot reproduce, it looks like an installation issue. Could you try updating to KDE 4.14.3 and report back again?

Comment 3 Christoph Feck 2014-11-19 20:54:53 UTC

Are you using BTRFS (default on fresh openSUSE 13.2 installations)? It could be related to bug 340657, if KSycoca uses mmap for the configuration cache.

Comment 6 andrepontes 2014-12-13 14:04:21 UTC

Yes, I'm using Btrfs.
But the problem only occurs when opening non UTF-file. 

this attachment https://bugs.kde.org/attachment.cgi?id=89943 can be used to reproduce. This is a non UTF encoding small text file. Do file save from browser, then try to open it on kwrite.
