Screenshot of problem
See steps and attached image.
Steps to reproduce:
1. Go to Tools > Customise > Toolbars, and click Add.
2. Move to a toolbar that does not have enough elements to fill the pane, e.g. Data. Now back to something that has, e.g. Application.
3. Keep switching between toolbars.
4. Watch the commands pane gradually shrink and then disappear.
The pane shrinks for toolbars with fewer elements and then stays shrunk when going to a toolbar with more elements.
The pane remains the same size regardless.
Platform (if different from the browser):
Ubuntu 11.10 Oneiric stable 32-bit
Browser: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
_NOT_ reproducable at upstream libreoffice-3-5 branch-off without Ubuntus default theme.
reproducable with 1:3.5.0-1ubuntu4 with Ubuntus theme.
Also not reproducable on upstream master (1cf3e446744ae679bc89b39dcbbcf6b4e9821f3a) without default Ubuntu theming on oneiric.
Also not reproducable on 3.4.5 Ubuntu build on oneiric.
This seems to be a regression between oneiric->precise in either Ubuntus theme or stack (gtk?)
resolving here as not our bug.
Of course, it could well be that it is a bug in the libreoffice gtk-vcl plugin which only shows with recent versions of gtk. In that case, please reopen.
@Fedora, SUSE user: Can you reproduce this with a very new gtk? The issie is visible here with gtk+-2.24.10-0ubuntu4
