System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 770/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 399.24

Blender Version
Broken: version: 2.81 (sub 12), branch: master, commit date: 2019-10-01 19:51, hash: 3b23685c7d
Worked: (optional)

Short description of error
Bsurfaces crashes Blender when two lines are drawn on the mesh and then pressing add surface from the properties panel. (It doen't crash if you press the same button on the tools N panel)

Exact steps for others to reproduce the error

On the properties panel press initialize
Draw two lines
Press add surface on the same properties panel
Blender crashes

PS: Could we have the option to keep an offset on the shrinkwrap modifier, also On Cage activated on the same modifier and on visibility have the option to have in front unchecked please? Every time I change settings on the mini panel it resets everything. It would be great if it could be able to set the color of the new mesh bright red and display set to object color too. That way we can press just one button and start retopo immediately. Many thanks!!

@cwolf3d : could you check D5974? Maybe thats enough already... (or just remove the custom tab name feature entirely? not sure what that was for...)

Thanks for the work. D5974 solves the problem. But if the user again wants to put the panel in Tools, the problem will pop up again. I will work on this issue.

Why not get rid of this entirely [the custom tab naming]? IMO, those tools should never show up outside the view3d, so giving the User any posibility to put it in the Tools category will just go wrong.
Are there any other addons with this 'feature' [the custom tab naming]?

This is not only a problem with this addon. Other add-ons can be installed in the Tool and at least they will not work correctly due to incorrect focus. When we click on the buttons in the addon, we are not in view3d.

Which [officially supported] Addons can be installed into the Tool category?

The name itself is a useful thing for customization for work processes. Need verification in adons or in Blender code. It must be prohibited to indicate the official tabs.

These are all addons where the use of panel.bl_category is found.

The list of add-ons is quite large:

animation_animall.py \scripts\addons
curve_assign_shapekey.py \scripts\addons
mesh_auto_mirror.py \scripts\addons
mesh_bsurfaces.py \scripts\addons
mesh_looptools.py \scripts\addons

In principle, introducing verification in these add-ons is not a big deal. I can add it everywhere today. I think you should not add this check to Blender code. It is an addon problem that it does not handle this behavior.

And the fact that Blender does not just throw an error but crashes is bad. Maybe this problem will give more insight into the Blender crash.

This issue has been resolved. This addon can no longer be enabled in the panel 'Tool'

Thanks!! found a bug, settings keep resetting to defaults after using the mini panel, also would like for the on cage button to be on. Many Thanks!

One more thing can you set the snaps on like this? Also I think the default offset is a bit too high, 0.01 is a might be a better value.

Thanks again!!

Prohibited the placement of this addon in the "Tool". I fixed a lot of bugs. Implemented all the wishes.
