OSM reports error after aligning nodes into a circle

[D4RKL3G10N]

The problem most likely occurred when I attempted to align the nodes of a circle with command 'B' (distribute nodes), causing the nodes to align into a line. Next I attempted to revert it with command 'O' (align nodes in circle), causing the now aligned nodes to heap into a single position (as if all nodes were in the very same spot). OSM reported an error at this moment.

I tried reproducing the error with the commands I described above, but I wasn't able to. The nodes did nonetheless heap into a single position but the dialog box didn't pop up again. It didn't make OSM crash, and after closing the dialog box I resumed working as usual, but since it ordered me to file a report, I felt compelled to do so, since it might help you guys out in the terrific job you're doing coding OSM.

Actually I could use this opportunity to recommend an improvement in command 'B'. I intuitively used in on the circle expecting that it would distribute the nodes equidistantly, as it would do for a line, but apparently for circles it doesn't, and instead heaps the nodes together into a line, 'destroying' the circle.

For me to doesn't look like anything crucial, much the opposite, looks like a quite minor error, if it is actually an error. So take your time and prioritize other errors, if there are any, since the latest versions of OSM have been quite bug-free. I salute all of you fine programmers for that!
