Has this always been a problem, or is it a regression? In other words, was there an earlier version of Blender where this feature worked as you expected it too?

@Sergej Reich (sergof) I don't know much about the physics. Is this feature being used correctly? If it is, is this a limitation of Bullet, or is it something we can possibly fix?

This is a regression, it's been broken somewhere after 2.70.
My guess would be that the way softbodies are constructed by blender has changed.

Looking further into it, culprit seems to be rBdf1a199, settings in blenderobject->bsoft are now completely ignored.
Here is a quick patch:

Thanks for the lead @Sergej Reich (sergof)! It looks like the code to copy these settings got lost in a recent cleanup. It makes me wonder if anything else got lost...

i have no clue how to install the diff file here.

@Skylyn Bilén (skyliner_369) to use a diff/patch you need to compile your own version of blender
However, in this case that should not be needed as moguri applied and committed the patch for everyone. You simply need to download a daily build that already has this change:
