A few days ago I probably reported the same bug, but I cannot find it now. Strange. I just wanted to write there the problem has been probably fixed – yesterday I installed a daily build and discarding worked there very well.

(I use Kubuntu 15.04 upgraded from previous versions and yesterday I added ppa:kubuntu-ci/stable)

Comment 2 Anton 2015-10-06 07:28:19 UTC

Thank you, Jan, I will try the new build.

Hi, can't reproduce either with e.g. Kate 15.12.

Please reopen and provide some hints how to get that crash with recent versions, thanks, and sorry for the problems :/
