Re: gerbv crashes (was Re: gEDA-user: gerbv 1.0 on RH8)

[Stefan Petersen <spe@xxxxxxxxxxxxxx>]

Hello again!

According to your gdb dump it segfaults in a function called 
'update_statusbar' when calling 'gtk_label_set_text' in gtk.

This can not happen, it is impossible. At least not where gdb dump 
shows. Broken gtk/glib/libc?

Anyone has any ideas or experince with RH8?

Sorry for asking which version on gerbv since I now noticed the 
subject of this email. ;-)
