I entered "gdb" and took a look at the backtrace, here's what I get:

Cannot reproduce it here:
Version 3.6.0.4 (Build ID: 932b512) Slackware Linux 13.37

Steps taken:
1. Started Firefox in full-screen mode.
2. Switched the scalc by using alt+tab.
3. scalc doesn't crash.

Lifecycle of 3.4 has ended. No more comments from reporter, so seems WFM?

@reporter:
Please feel free to reopen this bug if you find out that the problem still exists with the current stable LibreOffice version and if you can contribute requested additional information due to <http://wiki.documentfoundation.org/BugReport> (especially BugReport Details); "start another application in "full screen" mode" is very general, please descriibe more detailed)!
