code blocks fail and makes zim instable

[lalebarde]

When I try to use code blocks, it works find while I remain in the same page. Syntax highlighting works. As soon as I change page and back, syntax highlighting does not work any more and zim is unstable. For example, clicking on a menu opens it, but it never closes, whatever I do. I cannot edit any page. I have to quit zim, edit the file to suppress the code block by hand, and it works well again.

Here, I have used zim 0.65. I have also tested 0.62 from Debian Jessie repository. The bug is the same with a small difference, in 0.62, the code block squeezes from right to left letting only one character wide visible.

Included in the 7z archive:
  - a zim -D session including the add of a code block, then go to another vim page and back.
  - snapshot of the code block at creation
  - snapshot of the code block when back to the page
  - zim crash

Reading the other posts and testing, turning off the line numbering solves the issue.

Hi lalebarde,

I had the same problem. When I add a code block, the snippets dispalys as expected. But after I close zim and restart it, the code block displays as '{{{code ....}}}'. I have tried to trun off "show line numbers", the problem remains. Final, I changed the source view configuration in Edit->Preferences->Plugins->Source View->cofigure, disable "Show right margin" feature, and the code block dispalys back, everything sames all right. :)
