Please get in touch with us at any of the other support channels – https://helpx.adobe.com/support.html . Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.

I don't have privileges for the Radar, if that's what you mean, but I have uploaded the package here:
The instructions to reproduce:
1. Edit the Paragraph Style "Back Cover"
2. Select "Tabs"
3. Move the leftmost tab to 3pt, and the rightmost tab to 9pt
That's when you crash.Tim Walters commented
I take it back: I found the file. And I have a reproducible case: edit the paragraph style "Back Cover", set the leftmost (right-justified) tab to 3 pt and the rightmost (left-justified) tab to 9 pt. Unfortunately, I don't know how to upload the file at this point. For that matter, I have no idea why this is an "idea" rather than a "bug": I hit the Bug Report button (with the ladybug on it).
