I've had a problem with libreoffice - it won't open files. That is,
File/Open doesn't bring up a dialog box. File/New works and so does
using a filename on the command line when starting libreoffice.

Now there's good news and bad news. The good news is that with help from
some libreoffice-users folks, I now know what caused this and I have a
workaround. The bad news is that it's a bug in Libreoffice and I need
some help testing other versions, please. So here's the steps to reproduce:

(1) Login to a Gnome session (KDE may also work, dunno)
(2) Start libreoffice
(3) Select Tools/Options/LibreOffice/General
(4) Observe in that page a checkbox 'Use LibreOffice dialogue boxes'
(5) Ensure the checkbox is blank (not selected)
(6) Save settings and check that File/Open pops up a dialog box.
(7) Quit libreoffice and log out of the session
(8) Login to an LXDE session
(9) Start libreoffice
(10) Select File/Open
*(11) Check whether a dialog box appears
(12) If not, select Tools/Options/LibreOffice/General
*(13) Check whether there is a checkbox 'Use LibreOffice dialogue boxes'

If your system does NOT open a dialog box in step 11 and does NOT have a
checkbox in step 13, you are seeing the same bug as me.

I'm using opensuse 11.3. So I'd appreciate any confirmation or
contradiction on 11.4 or 12.1 beta if anybody's able.

Cheers, Dave

PS The workaround is to login to a Gnome session and select that
checkbox, then go back to LXDE and it all works.
