Short description of error
If right click on a custom property that has a string value you will get a "Reset to Default Value" option.... selecting it crashes Blender

Exact steps for others to reproduce the error
I've uploaded a simple file, the cube has a custom property... reset it to default value.

Have no idea, is there is why to check logs/error?

does not happen when the property was just created. Could be related to saving/loading.

I am see it happening in the file, but I am not able to reproduce it from scratch. Do you know the steps that were taken in order you got the file in this state that crashes?

I literally just create a custom property then try reset it to default.... I'll try get another user to confirm...

This is in a fresh blend...

Can confirm this, too.
Not sure why I am not getting it all the time (sometimes I have to try twice), but on second try, it always fails.
With a debugger attached, it seems to always fail.

Note this was once reported before #54899 (Custom property -> revert to default value crashes blender), I wasnt able to reproduce for a while later, so closed it, but seems to be back (or never fixed...)

@angavrilov : you did 61c941f040, mind checking if P669 is safe enough?

I can even reproduce this in 2.69... it's a fairly consistent bug ;)

....even the removal of the ability to to run a "Reset to Default Value" for strings would considered a fix.

Yep, can confirm this is happening in the supplied blend.
I can also reproduce it in new blends. I've tried adjusting various settings(like setting or clearing a default value) of the prop before attempting to reset to defaults. Sometimes it would not crash, but I could not find a consistent method to do this.
