a debug version (./configure --enable-debug) should dump an automatic

This gives me a "ptrace: Operation not permitted." But running the
program in gdb I get the attached backtrace. (Running r2665, latest from
trunk there.)
does this crash-on-record happen with prior builds, before your patching
suggestions ?
Yes, it's already in the 0.5.3 release. The stock Ubuntu 11.04 version
of qtractor (0.4.8) works fine, though.
I also get segfaults when closing the GUI of LV2 plugins (e.g., calf
organ). I don't get these with 0.4.8 either, and they work fine with
Ardour3 as well. But maybe I should start filing proper bug reports now. :)
