Options windows after crash
Start LibreOffice -> Tools -> Options; Click on proxy under Internet - LibreOffice crashes.
This is on a Dell Inspiron 580 Core i3, 4GB RAM, Microsoft Windows 7 Professional 64 bit with Java 1.6.0_26-b03
First: Judging from your screenshot this is not a crash, the software just hangs. (Not that it'd make much of a difference to you being able to use LibO – but "crash" means that the software unexpectedly quits. I edited the bug title.)
Second: can't reproduce with LibreOffice 3.5(.0) on Windows Vista (32-bit).
Do you have any special proxy settings set in Windows?
I would still prefer the term crash since the main LO window does disappear leaving behind just the window shown. I do not have any special proxy setting requirements but was trying to understand why the update feature was reporting unable to connect when the internet connection was / is fine. I have also added a comment at bug 43989 which also happened in my installation (twice - re-installation after complete cleaning of Program Files folders and registry settings using regedit and CCleaner). Overall I seem to be having multiple crash problems with LO 3.5.0 which was not the case with the 3.4.x series.
From the other bug, it seems this is indeed a crash...
