Comment 1 rebuilderster 2016-02-02 09:48:12 UTC 
On further exploration, it seems this is because the file I was working on had parallel ruler assistants that had been saved with the file when I last worked on it. Removing the assistants and setting new ones results in Krita no longer crashing.
Comment 2 wolthera 2016-02-02 09:50:41 UTC 
This bug has been fixed in 2.9.10. Try to see if you can update using the krita lime repo, or by building using the cat-guide. Last option is to wait for 3.0 to come out as that has portable linux packages.(pre-alpha is already out on the website under the new posts)
