[Java-gnome-developer] glib fatal error using a FileChooserButton

[Guillaume M. <res...@gm...>]

Hello (and happy new year),

I developed an application that is working great for people and me. But
today, one person reported me a bug. An exception occurred when a dialog
which contains a FileChooserDialog is built. Here is the stacktrace:

org.gnome.glib.FatalError: GLib-CRITICAL
g_bookmark_file_load_from_data: assertion `length != 0’ failed
at
org.gnome.gtk.GtkFileChooserButton.gtk_file_chooser_button_new(NativeMethod) 
at
org.gnome.gtk.GtkFileChooserButton.createFileChooserButton(GtkFileChooserButton.java:41)
at org.gnome.gtk.FileChooserButton.<init>(FileChooserButton.java:57)
at
org.gnome.split.gtk.dialog.PreferencesDialog.createSplitPage(PreferencesDialog.java:336)
at
org.gnome.split.gtk.dialog.PreferencesDialog.<init>(PreferencesDialog.java:124)

at org.gnome.split.GnomeSplit.<init>(GnomeSplit.java:141)
at org.gnome.split.GnomeSplit.main(GnomeSplit.java:211)

I can't figure out why, this person had this error.
Does someone know why this exception occurs?

Thank you for your help.
Cheers.

Guillaume and I chatted about this briefly earlier today; the crash
doesn't occur for either of us, so it's hard to say what this is.
Searching around a bit, the only other mentions of this problem seem to
be from a few years ago relating to something the Compiz specific
gtk-window-decorations helper was doing. No idea if that's relevant.

Maybe the user has a old version of GTK or GLib installed?

Hello,

I found why that crash occurred. And it is pretty easy to reproduce.
Go in your home folder and then:

~$ rm .recently-used.xbel
~$ touch .recently-used.xbel

or even (but it is stupid)

~$ mkdir .recently-used.xbel

Start your program with a file chooser widget and then it will crash. I
tested with a program written in C and it does not crash but it warns
you about that ".recently-used.xbel" file.

I don't know if we should really consider this as a bug because if the
user uses his/her desktop right it should not happened... But if we can
do something to prevent the program from crashing it could be nice.

Ok, so, that's weird.

Before we go any further, why would that file ever be empty? Isn't is
part of a default [ie new user has logged in for the first time] GNOME
install?
