FileChooserButton forgets file filters

[Helge Stenström]

A file filer is set to a FileChooserButton. The first time the FileChooserButton is clicked, the filter is there and works. The second time, the filter is gone. This can be confirmed by the FileChooser.list_filters() method, or by the look of the FileChooser dialog.

Expected behavior: The file filter is persistent.
Observed behavior: The file filter disappears after the first activation of the FileChooserButton.

Unknown if this is caused by the "button" or by the FileChooser.

Attached: small demonstration example.
Tested with Ubuntu 8.10 and python-gtk2 version 2.13.0ubuntu8.

thank you for your bug report, is that specific to pygtk or do you get the same issue in C? should probably be sent to the people writting pygtk on bugzilla.gnome.org

[Helge Stenström (h-stenstrom)]

I have not tested on C, because I'm not comfortable with C and compiling stuff. I have not tested with Ubuntu 9.04 either, yet.

[Sebastien Bacher (seb128)]

changing the bug to NEW but it could be a programmer question rather than a bug

[Helge Stenström (h-stenstrom)]

I've filed a bug upstream, as proposed. http://bugzilla.gnome.org/show_bug.cgi?id=580321
A comment there is: Cannot reproduce here. This was most likely a GTK+ (not PyGTK) bug that was fixed at some point.

could you try on jaunty?

[Helge Stenström (h-stenstrom)]

I have now tried in Ubuntu 9.04 (Jaunty), and the problem remains.

[Sebastien Bacher (seb128)]

you should comment on the GNOME bug to say that

[Helge Stenström (h-stenstrom)]

OK, I've told them. But the bug was marked as obsolete, when I had only tested with pygtk 2.13. I don't feel confident that this is not a programmer error, as I am a beginner with gtk programming, and only a python hobbyist. But my demo program is fairly simple. Everything that happens, happens inside gtk.main().
It would be interesting to try on another Linux distribution, and to try on Ubuntu, but in another language.

[Helge Stenström (h-stenstrom)]

The demo program works as expected on Solaris 8, with Python 2.5.1 and (probably) pygtk 2.10. So it's not a programmer error. Remains to see if the error is in pygtk or in gtk.

[Helge Stenström (h-stenstrom)]

The demo program is now translated to C, tested on RedHat 4, and it fails. This seems to be a gtk problem.

confirming on jaunty
