Maybe you shouldn't let KATE operate things if she is
crashing them. Not Debian kernel compile/build related.
Go to KATEs devs with your issue.
The Debian-KDE list is, by definition, not kernel related.
Saying don't use a buggy program is silly. Every program has
some bugs so you are saying "don't use computers". Besides, if
everyone stopped using a package, how would we know when a bug
was fixed?
Referring the issue elsewhere gets us into the blame game. Is
the problem particular to the Debian-KDE package or is it
generic? The Debian packagers are the ones best positioned to
figure that out and either fix the package or send it upstream.
The Debian packagers need to know when a package is stable
enough to make it into the next stable release. If they don't
get bug reports, how can they make that determination?
