4.0EA3 Can not view Snippets

Question

Hi!
The View menu does not have the "Snippets" entry any more. I made sure that option in Tools -> Features -> Database -> Oracle SQL Developer - Snippet is checked, but the entry does not show in the View menu. I also tried to toggle the option off and back on  (and restarting SQL Developer after each change), but to no avail. I also tried to start with fresh set of preferences by deleting my ~/.sqldeveloper/system4.0.0.13.30 directory, however the snippets did no show up.
This issue is happening on Centos 6.4. 64bit with JDK 1.7.0_40.
Funny enough, at home on Debian 7 32bit with JDK 1.7.0_45, the View menu has the Snippets entry and it shows Snippets just fine!
The database connected to is 11.2.0.3 64bit.
Please, help me get my snippets back!

Hi Gary,
Summary first: I've got my snippets back! It was a bad extract from the rpm installation file. Here are the gory details for those who like to be entertained.....
You've got me thinking, that something may be different between windows and linux versions. Since both are java, the windows version should run on linux, too - right? Here's what I did:
downloaded the windows version
unzipped it in an empty directory
made sqldeveloper executable (chmod u+x sqldeveloper.sh)
added AddVMOption -Duser.home=/home/alex/tmp/sqldevwin to sqldeveloper.conf to force it to use a new profile
run sqldeveloper.sh (it started up just fine!)
created a connection to make it open a new worksheet
check the view menu - and snippets entry is there - and it displays the default snippets correctly
exited sqldeveloper
copied UserSnippets.xml from my linux profile to the new windows profile
started sqldeveloper again, checked the snippets, and my snippets are there, too!! Yay!
As far as I can see, there are two files missing in my linux install when I compare with what is found in extensions directory in my windows install:
oracle.dmt.dataminer.jar
oracle.olap.jar
Then I disabled the following features and restarted SQL Developer, just to check the Gary's suspicious about a possible bug:
miner
olap
change management
restfull services
spatial
times ten
unit test
xml schema
all database migrations
version control
After the restart, snippets are still correctly displayed!
So I checked if those files are missing in the downloaded linux rpm. When I opened the file with Archive Manager (File Roller 2.28.2), those 2 files were in there! I extracted the archive in an empty folder - the files are missing! Obviously, File Roller is messing things up (no shortage of space, no errors reported). Since I usually install this way, now I see why my installation got hosed. I extracted the installation files from the rpm with:
rpm2cpio /home/alex/down/sqldeveloper-4.0.0.13.30-1.noarch.rpm | cpio -i -d
Check the files, they are where they're supposed to be. I guess I'll have to talk to developers of File Roller why this is happening.
Gary, thanx for your help and guidance!
