Crash does not occur with "classic" (not Sidebar) stylist because if there is no bullet, command (in step 4.) is unavailable, which is correct.

Crash occurs because there is no bullet, so there is no List style to create.

With LibO, the command is available, but the created list style is hidden. Select another style type and come back to List Styles. Created list style contains numbering bullets.

From my point of view, the "classic" stylist has correct behavior: command should be unavailable if no bullet/numbering is selected.

Reproduced with LibreOffice, windows XP X86.

With "sidebar" styles window, "New style from selection" for List Styles is not grayed out. When enter a name and press ok, crash.

With the classic F11 style window, "New style from selection" for List Styles is grayed out so no option to enter a name.

Reproduced with LO / 7 x64

On pc Debian x86-64 with master sources updated yesterday, I don't reproduce this.
However, I noticed this trace on console:

Comment 9 famo 2014-05-28 08:46:42 UTC
I still (or again?) have this issue in LO Impress.

LO Impress hogs 100% CPU and hangs forever on creating a new style.

How to reproduce:
1. Start LO Impress (New Presentation)
2. On the right choose Stylist
3. Right click on Titel and choose New...
=> LO hangs

Reproducible always.

I tested on Win7 and Linux both 64-bit.

I reproduce your steps in Impress, libreoffice My steps:
1. New Impress;
2. Enable sidebar, Styles and Formatting;
3. Right click "Title", New.

Current Behaviour: Impress crashes.

I also tested in 4.3.0 beta 1, the wired thing is that: at step 3, there is no crash, but the create new style window do not pop up (no reaction).

Although I can reproduce you steps, this bug is about "New style from selection", but the reason to reopen this bug is "Create new", they are different issues.

So please file a new bug report, add this bug as see also.

I will file another bug regarding the "create new" no response for 4.3.0 beta1.
