Summary0000518: mmc; binding faders causes segfault
DescriptionArdour/GTK 0.515.0 running with libardour 0.815.0

Paul, will catch up to you on IRC tomorrow. There's some easily reproduced segfaults. If no midi port connection, then attempts to bind fail, after failure mouse clicks on the fader cause Segfault.

this is still happening. i think the new backtrace is similar to the one in the report:

the code for this has changed so much that if the bug still existed, which i doubt very much (cannot reproduce ever), then it is a different bug.
