[ardour-dev] Segfault with current SVN (rev: 639)

Sun Jun 25 11:00:36 PDT 2006

Hi!

It has been a while since I used ardour, however must say that ardour2
looks just great! I'm impressed!!

After fighting a while with scons, recompiled glib-2.11 for SuSE 10.1,
finally managed to bulid ardour2.
Playing around a little bit, in the new UI when setting a track for
recording and pressing the record button I got a segmentation fault,
the stack look like the following with GDB:
