Bug#523353: stellarium: Segmentation fault backtrace with libqt4-dbg

2009-09-12 Thread Andreas B. Mundt
Hi Julien,

On Sat, Sep 12, 2009 at 07:21:08PM +0200, Julien Cristau wrote:
 Any chance you could install libqt4-dbg and get the backtrace again?

Here we are, with libqt4-dbg installed. Could you give a short hint
from which line(s) you determined the need of libqt4-dbg? (Just to be
able to learn something...)  

Thanks,

Andi

The backtrace pointed at /usr/lib/libQtOpenGL.so.4, from the
libqt4-opengl package, whose debugging symbols are in libqt4-dbg.

The new backtrace seems to point at some realloc in freetype…

Cheers,
Julien
