Description mvowada 2015-02-03 01:43:24 UTC 
I get a crash:
1. by closing a document 
2. with a line layed down on a "Vector layer" which is nested inside a "Group layer"
3. the line having the outer end, marked with the eighth arrowhead starting from the bottom of the drop-down menu of markers

Ubuntu 14.04 Unity - Krita 2.9 Beta 2 (git 9715bb5)

Reproducible: Always

Steps to Reproduce:
1. create a vector layer inside a group layer
2. create a line with the Line Tool
3. select the line
4. Tool Options panel > Line > and set the outer end of the line with the eighth arrowhead marker, starting from the bottom of the drop-down menu.

Actual Results:  
Krita crash on close

Judging from the backtrace, I think this is exactly the same bug as https://bugs.kde.org/show_bug.cgi?id=343515, but this report makes it easier to to reproduce :-)

Meh... I still cannot reproduce.
Comment 5 mvowada 2015-02-03 21:17:45 UTC 
Thank you. Here after updating to krita 2.9 Beta 2 (git 066c942), I'm still able to reproduce the problem. I'm wondering if it's something related to my system... :| I'm on Ubuntu 14.04 Unity

Comment 7 Halla Rempt 2015-02-03 21:20:22 UTC 
No... The backtrace is pretty clear: it _is_ a problem in the memory management of marker objects. I'm just to dumb to reproduce it, let alone fix it. What is happening is that the marker get deleted twice, I'm pretty sure of that.

No problem :) Thank you!
