Most likely caused by "fix" for bug 402764.

Caused by bug 402764

This didn't happen in my testing, but appears in my main Luna workspace as well.

I'll have a fix in a moment.

Same here. I updated to I20140226-1700 and after restart I lost my carefully crafted perspective :(

To save your layouts, you have to copy your <workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi somewhere safe before exiting eclipse (and within about 5 minutes).

I'll ask David for a respin.

I had a backup of workbench.xmi and after replacing the corrupt workbench.xmi with the one from backup, I tried to open my workspace with an old I-build.
I did not get the state back. Is there anything else that should be done?

Making sure eclipse is shutdown, replacing the workbench.xmi, and then starting up an old I build is really all you can do.  You can check the logs to see if it failed to load, I guess.
