[Ktechlab-devel] KTechlab 0.3 crash/backtrace

[Mike Dunn (ktechlab)]

Hi folks,

I've just finsished installing revision 0.3, and have run into a bit of
trouble with the GUI.  Let me first say that I'm new to KTechlab, and are
practically inept with electronics, so I'm certain that I'm doing something
wrong :).

The problem occurs every time I touch the "restart" arrow (the right most
blue button, under a PIC in the circuit view) on a PIC.  Ktechlab crashes,
and I immediately get the back trace pasted below.  I could also provide a
screen shot and/or the circuit files that I was working with.  What other
information should I provide?

System:
Gentoo (2.6.12.5 kernel, x86)
X11 6.8.2, KDE 3.4
GPSIM 0.21.11, glibc 2.3.5

  Thanks!
  Mike Dunn
