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.

This bug exists in different zim versions and fedora versions :
In Zim0.56-1.fc16 https://bugzilla.redhat.com/show_bug.cgi?id=822638
In Zim0.56-3.fc17 https://bugzilla.redhat.com/show_bug.cgi?id=875712
In Zim-0.57-1.fc17 https://bugzilla.redhat.com/show_bug.cgi?id=875734

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.

[Jean-Baptiste Holcroft (jibecfed)]

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.

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.
