I did a trace of when it crashes and when it succeeds and it looks to be a race condition between threads.

445.648 (17691.208 ms): krita:traceq0/27972 ... [continued]: futex()) = -1 (unknown) (INTERNAL ERROR: strerror_r(512, [buf], 128)=22) 16916.626 (1220.284 ms): Thread (pooled/28016 ...

[continued]: futex()) = -1 (unknown) (INTERNAL ERROR: strerror_r(516, [buf], 128)=22)

those messages do not show up in the working dump and there are a lot of error messages about futex

this is the bottom of where it crashes

I will note that in the trace where krita works there is no xdg-desktop-po messages at all

[devilsclaw]

So I was able to fix the crash with a work around.

cd /usr/share/krita
sudo mv pykrita pykrita.bk

After that krita does not crash anymore. So it seems to be related to pykrita

also new messages show up while running it from console after last nights update. it also crashes more like 9 out of 10 times now for me.
