Bug Description


libreport version: 2.0.8
abrt_version: 2.0.7
cmdline: /usr/bin/python /usr/bin/zim
comment: I had been pasting bulleted lists from Tomboy, then reformatting in Zim (since they paste poorly). Here I was at the last pasted bullet (indented one level), on the last line of a Zim note, when I hit enter to add more information.

You just have to play with symbols "(" and ")" and adding/removing items in numbered list a few times.
I'll try to make a video to show how to repoduce.

  • Video Edit (7.1 MiB, application/octet-stream)

If you play a little bit with the lists, you crash zim easily.
I hadn't exactly the same crash in "normal" use of Zim.
In "normal" use, I just added an internal pagelink between "()" and inserted a line return.

Thanks for your help.

Need further investigation. Probably can only fix by refactoring the code for maintaining lists.

tags: added: lists
Changed in zim:
status: New → Confirmed
importance: Undecided → High
tags: added: pageview
removed: lists

Toggle Strong off for some line in a bullet list. And then type enter to try to create a new entry of bullet list. But Zim does not add a bullet in the front of new line and then dump a call trace.

Changed in zim:
importance: High → Medium
