Bug#738352: gedit: Gedit crashes in open file dialog when I run an intensive process that access many files in the directory currently open in the dialog

Sun Feb 9 13:25:05 UTC 2014

Package: gedit
Version: 3.4.2-1
Severity: important

Dear Maintainer,

My specific steps to repeat - this can probably be distilled a little, but everything reported in case the context is important:

0. Run gedit from command line on my home directory
1. In another terminal run apt-get source on some package and change into it
2. From gedit, open a file in the package source root
3. From gedit, open a file in the package debian/ directory; this sets gedits CWD to debian/
4. From gedit, open the file open dialog, change up one level to display files in the source root, and leave it open
5. In the terminal, start to build the package, for example dpkg-buildpackage -rfakeroot...
6. In the gedit file open window, scroll the file list or do some other manipulations, and in fairly short order, it will segfault

In abstract, it seems that gedit file/open dialog doesnt lots of like other stuff happening in the directory it is displaying

There are at least two different assertions that can occur:

Gtk:ERROR:/tmp/buildd/gtk+3.0-3.4.2/./gtk/gtkfilesystemmodel.c:751:gtk_file_system_model_sort: assertion failed: (r == n_visible_rows)

or

Gtk:ERROR:/tmp/buildd/gtk+3.0-3.4.2/./gtk/gtkfilesystemmodel.c:328:node_set_visible: assertion failed: (row < model->files->len)

The first assertion generates the following stacktrace:
(gdb) bt

I subsequently rebuilt the package from source with DEB_BUILD_OPTIONS="nostrip noopt" and obtained the folllowing stacktrace on the second of the above assertions:

Both assertions occur, but which of the assertions occurs appears to be random, I cant narrow it down exactly.
