Hey Starius,

I couldn't reproduce this. Prior to your call to closeEditors(), is there any other manipulation to the view or model you did within the same event ?

Regards,
koen

Hello!

I tried to create an example to reproduce this and probably discovered another segfault.
The program ends with segfault after trying to edit any field.

Hey Sarius,

I've fixed this, in git. I suspect it could be the same issue if you were also use setRowHeaderCount(1) in your other test case ?

Regarsd,
koen

Hello,

Yes, setRowHeaderCount(1) was also used in other test case.
