Problem with kate closing

CPB
I have had a problem with kate crashing X from scrotwm.
I have also had another problem with kate that does not crash X.


I also built kdebase and scrotwm with debugging

I haven't been able to reproduce that X crash again.

However, I have noticed an easily reproducible problem with kate.
When I close with Ctrl-Q, shuts down just fine.
If I use Alt-f, then q, it consistently and usually crashes (kate, not X).

I have included the backtrace that kde supplies:

I'm seeing this too when I use alt-f q but not when
ctrl-q.

Base and packages updated yesterday:

OpenBSD 4.6-current (GENERIC) #512: Mon Jan 25 10:08:42 MST 2010
     [hidden email]:/usr/src/sys/arch/i386/compile/GENERIC

I saw some patches after googling a little, they might help.
Don't have time to test yet myself. I searched for "kate crash exit".

Hi,

could you try the following patch against kdebase to
see if it fixes kate's crashing.

For me kate crashed when I selected previous session
and exited with alt-f-q, not when I started a new
session. The patch fixes it for me. It's from KDE's bug tracking,
issue 183356: https://bugs.kde.org/show_bug.cgi?id=183356

I attached it inline, and it's also available at:
http://openbsd.fi/iku/files/kdebase.diff

Looks like it works fine
