Bug#733927: librecad: SIGSEGV when measure distance

[Andreas Weber]

Package: librecad
Version: 1.0.2+nolibs-1
Severity: important
Tags: upstream

Dear Maintainer,

* start librecad
* left mousebutton click on "Show Menu 'Info'"
* left mousebutton click on "Abstand (Objekt, Punkt)"
* right mousebutton click on "Restrict nothing"

Do this repeatedly until you get a segfault
(sometimes one the first try, sometimes I need to do this 3 times until it
segfaults)

I think the backtrace without debugging infos isn't very usefull but here it
is:
Program received signal SIGSEGV, Segmentation fault.
