There's a problem with changing the target of a TOC entry in the TOC editor.
- Choose: Tools -> Table of Contents -> Edit table of contents ...
- Pick any entry in the TOC
- Click "Select Target"
- segfault
The segfaults every time I've tried it in a number of epubs, including my sample 50 little image epub, a Calibre news recipe and "normal" books.
Maybe I should change my profile blurb to "I break things"?
