1. tried running it from a clean account (so no specific environment variables and also no workspace yet) and it still crashes

2. env. vars.: see 1. above; tried openjre7 from Debian respository, Luna also crashes, see log below.

3. build version: I cannot determine this from the Eclipse GUI Help->About because it crashes before the GUI is activated (I only see the small startup flash window).

$ java -version
java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1~deb7u1)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

mdo@vapulo:~/Downloads/Eclipse/4.4 (Luna)/eclipse$ ./eclipse 
org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized.  Will retry after the state location is initialized.
