Bug#1079570: libgtk3-perl: Undefined subroutine &main::1 called at /usr/share/perl5/Gtk3.pm line 572.

[Dennis Boone]

Package: libgtk3-perl
Version: 0.038-3
Severity: normal
X-Debbugs-Cc: drb at msu.edu

The GCstar package, a collection management tool, is written in perl and
uses Gtk3.  The software seems to run correctly, however when the
program exits, it throws an exception and dumps core.  The terminal
output from a session looks like this:

```
ozymandias 949 # gcstar

(gcstar:511623): Gtk-CRITICAL **: 14:01:32.057: gtk_tree_selection_select_iter: assertion 'model != NULL' failed

(gcstar:511623): Gtk-CRITICAL **: 14:01:32.066: gtk_tree_selection_select_iter: assertion 'model != NULL' failed

(gcstar:511623): Gtk-CRITICAL **: 14:01:32.067: gtk_tree_selection_select_iter: assertion 'model != NULL' failed
*** unhandled exception in callback:
***   Undefined subroutine &main::1 called at /usr/share/perl5/Gtk3.pm line 572.
***  ignoring at /usr/share/perl5/Gtk3.pm line 572.
Error de segmentación (se ha creado un `core')
```
A gdb backtrace doesn't seem all that informative:
